10mm Ammo

It’s hard to dispute the quality of a company’s products when they’ve been in business for nearly two centuries. Sellier & Bellot, the Czech company who have kept their factory doors open since Queen Victoria was only six years old, are globally recognized for their ammunition’s performance -- you can find their stuff practically anywhere that firearms can be found.

This 10mm cartridge features a non-corrosive Boxer primer, factory fresh and reloadable brass casing, and clean burning propellant that will keep your bore and action intact. Its 180 grain projectile is a balanced weight for its caliber, giving you a comfortable shooting session without sacrificing power. This bullet’s copper alloy jacket will prevent your pistol’s rifling from becoming gummed up with lead residue, and its flat nose not only ensures reliable feeding in semi-automatic weapons but also punches clean and easily spotted holes through paper targets. Give these 50 rounds a shot and Czech out why Sellier & Bellot has maintained their dominance in the ammo industry for such a long time!

A 10mm is by nature a powerful cartridge. You could make its bullets out of pralines or compressed goose feathers and it would still have the power to seriously jam up an assailant’s day. Heck, just wallop someone over the head with a 10mm handgun and all that’ll remain to do is phone the police and fill up a mop bucket.

This isn’t to say that a beefy hand cannon doesn’t still deserve a good cartridge when it comes to self-defense -- one exactly like this cartridge by Magtech. Its bullet is a 180 grain jacketed hollow point, which feeds and penetrates reliably and expands a great deal during penetration. Look closely at this bullet’s tip and you’ll see faint indentations which control that expansion to make it all the deadlier.

Magtech is one of the world’s biggest ammo manufacturers, and their tools and people are at the peak of the industry. These rounds’ new casings are reloadable, and their explosive parts don’t produce caustic residues when they explode.

The 10mm is not a good cartridge for the faint of heart. You, however, are strong of heart. Your heart warms up by benching four plates. That’s why you love the 10mm, and that’s also why you’re the perfect candidate to receive the whole dang case of Federal Champion.

This is a range load: surely capable of handling any threat to your safety, but less than ideal for defense owing to its full metal jacket’s inability to expand after impact. The 180 grain bullet cruises out of Federal’s 5” test barrel at a rate of 1,200 fps, which means it’ll drop about -3.3” below the bore line by the time it hits 50 yards. That’s a flat trajectory as far as the old 10mm is concerned!

Open up one of this case of ammo’s boxes and you won’t just see 200 Minnesota-made cartridges. You’ll also see 200 freshly drawn and cut brass cases – just the sauce you need if you’re a handloader. We’ll even sell you the bullets you need to reload this ammo!

The FBI deemed the 10mm “too hot to handle” for its agents. You love it, however, which means you’re considerably tougher than a great many FBI agents. And to all the FBI agents who monitor this website, we’re sure you have many great qualities that offset your inability to handle powerful pistol ammunition!

If your wrists are strong and your ability to appreciate high-quality American-made range ammo is honed, then you will appreciate this high-quality American-made range ammo. Federal tops each round with a simple 180 grain full metal jacket bullet. Normal recoil at 1,200 fps muzzle velocity (5” test barrel). No steel or other ferrous metals to attract a magnet. Just the ticket for range training at any range you’d care to train at.

Federal’s Champion line of ammo occasionally features inexpensive aluminum cases. This ammo, however, is loaded with fresh-as-puppy’s-breath brass cases. We’ve got just the component bullets you’ll need if you want to handload them!

You’re a good guy with a gun. But that doesn’t necessarily mean you are good with a gun. Only copious hours of target practice can make you that way.

If you’d like to make certain you’ll have the skill and confidence you’ll need in order to navigate a sensitive situation – i.e. the kind of situation the 10mm handgun was designed to make better – then you’ll definitely want to stock up on range and target ammunition.

Winchester’s USA series ammo gets straight to the point. No fancy bells and whistles. No flashy packaging or advertising gimmicks. Just copper, lead, brass, clean-igniting explosives and time-testing loading practices.

This cartridge is loaded with a 180 grain full metal jacket bullet, with a nonmagnetic jacket and a flat nose profile that will punch a neat hole through paper. Its 1,080 fps muzzle velocity gives the round comparable recoil and point of impact to an analogous self-defense load. The non-expanding projectile is seated in a reloadable brass case – brand new, with a noncorrosive Boxer primer. Ten boxes per case. Fast shipping from the good guys at Widener’s.

Enjoy shooting your 10mm Auto handguns while keeping costs under control with this dependable ammunition from Sellier & Bellot. These cartridges deliver solid performance on the range; each box contains 50 rounds.

This is a medium power load firing a 180 grain full metal jacket bullet at a muzzle velocity of 1,164 feet per second. While not the most powerfull 10mm load out there, this ammo definitely produces a kick along with nice, flat trajectories and excellent accuracy.

Sellier & Bellot ammo is made in the Czech Republic by CBC, which also produces the MEN and Magtech brands. S&B ammo uses non-corrosive primers and re-loadable brass.

This 10mm Auto cartridge by Magtech features a 180 grain jacketed hollow point projectile. The bullet’s jacket assists in smooth feeding in a semi-automatic weapon, strengthens it for certain penetration, and features notches circling its tip that precisely control expansion. A hollow point, this bullet will produce a gaping wound channel within a threat in order to neutralize it quickly, which suits it for effective hunting as well. The 10mm is inherently able to penetrate deeply, which along with this round’s ability to maintain its supersonic velocity a few dozen yards out guarantees its devastating terminal performance.

This round is loaded with a consistent charge of clean burning propellant, so it will behave predictably while sparing your pistol from rapidly fouling -- its non-corrosive primer is similarly conducive to clean shooting. Magtech’s brass casing possesses the uniform dimensions requisite for seamless cycling, and is worth scooping up off the ground for your next handloading session.

You don’t carry a 10mm pistol because you plan to come up short handed when the situation turns grim. This cartridge by Sellier & Bellot is just the one to compliment so beastly a handgun’s performance, because its 180 grain projectile is a jacketed hollow point. Its deep nose cavity and notched jacket will bring about a deep, gaping wound channel, the likes of which few human-sized threats (and vicious beasts, for that matter) will have the stamina to walk away from. Such a bullet is nicely a common weight for its caliber, so you can train with loads similar to it to effectively hone your skills with this self-defense round.

This cartridge’s brass casing is fresh out of Sellier & Bellot’s Czech factory, and therefore dependable during the first and several consecutive times it could be fired. Sellier & Bellot’s primer and propellant both burn cleanly, thereby lengthening the lifespan of your pistol’s action and bore. For the little it costs, this is a round you’ll be truly grateful to have on your side.

Wanna see us do a magic trick? Just click the “Add to Cart” button, and voilà – a whole case of Federal Premium American Eagle 10mm Auto ammo will appear on your doorstep in no time flat. Sure beats pulling a rabbit out of our hat!

American Eagle is Federal’s dedicated brand of target shooting ammo. We wouldn’t volunteer to get hit by any 10mm bullet. All the same, the full metal jacket is not designed for terminal expansion, and accordingly punches a ~4” hole into a soft medium instead of a significantly wider one. The 180 grain bullet achieves 1,030 fps muzzle velocity out of a 5” barrel, and reaches 100 yards with ~400 ft lbs of kinetic energy. The bullet has the 10mm’s iconic flat nose profile, which helps to punch a pretty clean hole through a cardboard or paper target.

Order today and you’ll soon take pride in owning true Minnesota-made ammunition. And if you want to put this ammo’s brand new brass cases to work at your reloading press, we’ve got just the component bullets you’ll need for the job!

This 10mm Auto ammunition is an economical hollow point load suited to boar hunting, self-defense, and target shooting. Each cartridge in this case of 500 fires a heavy 180 grain JHP bullet at a muzzle velocity of 1,197 feet per second.

Hollow points bullets expand on contact with an assailant or animal to produce rapid incapacitation; however, their semi-wadcutter shape also lends itself well to punching clean holes in paper targets as well!

Prvi Partizan ammunition is loaded in Uzice, Serbia and uses reloadable brass cases and non-corrosive Boxer primers.

These 10mm ammo from Remington uses a metal case that ensures reliable feeding and less fouling. This means you’ll be able to go through more rounds during your training and practice periods. The rounds not only have world-class bullets, they also use clean-shooting primers and factory-fresh brass cases. Loaded with 180-grain bullets, these rounds are a great choice for range use and in this 500-round package, you'll get 10 boxes with each containing 50 cartridges that are ready for trigger time.

Since 1816, Remington has been a leader in the world of ammunition. With excellent products for hunters, target shooters, law enforcement officials, and anyone concerned with self defense, Remington is trusted by gun owners all across the country. They not only have superior cartridges, they also create top-quality rifles, shotguns, and handguns.

The 10mm Auto is a handgun cartridge that was developed in 1983 and was used extensively by law enforcement agencies until the early 1990’s. Although it was mostly replaced by the .40 S&W, the 10mm Auto remains a popular choice for hunting, self defense, and target shooting, thanks largely to its outstanding power and terminal performance. It’s even used by a few elite law enforcement agencies to this day.

It doesn’t matter whether you’re demonstrating your mastery of a firearm during fierce competition or toning up your aim in private: You want to know exactly where you’re hitting the target. This 10mm cartridge by Fiocchi will let you do just that, as its 180 grain truncated cone projectile possesses a flat meplat which cuts a tidy hole through a sheet of paper. Because this bullet’s profile is tapered rather than cylindrical like a wadcutter’s, it isn’t difficult for a semi-automatic to feed it. Fiocchi’s evenly drawn full metal jacket complements the bullet’s aerodynamic design to promote an accurate trajectory as well.

This round’s bullet is flatly seated within a new brass casing, which is strong enough to resist splitting even after having been reloaded several times. Fiocchi’s attentive approach to loading has ensured that each of these rounds’ primers and propellant charges are virtually identical to one another -- expect consistent performance as you work your way through this case of ammo!

These 10mm rounds from Remington give you the performance and reliability you expect at the range. The clean-shooting rounds are excellent for training, as the 180-grain bullet with a metal case allows you to go through many rounds with less fouling in the barrel. When it comes to value, few 10mm Auto bullets can deliver like Remington’s UMC cartridges. Order a few of these 50-round boxes and you’ll be all set for a day at the range.

For over 200 years, Remington has been a top name in ammunition, creating options for handguns, rifles, and shotguns of nearly every variety.

The 10mm Auto was a precursor to the .40 S&W handgun round, which is used extensively by law enforcement agencies, both on a local and national level. While it was decommissioned by many organizations when the .40 S&W became available, the 10mm Auto maintains a popular following, thanks in large part to its excellent power and reliable bullet speed.

Picture a world without Jacuzzis, Moon Boots, opera houses, parachutes, or stilettos. Is that really a world that you want to live in? Thank goodness we were blessed with Italy, a country responsible for some of mankind’s greatest feats of innovation. Just to sweeten the deal Italy also gave us Fiocchi, which makes a wide variety of economical yet high quality ammo like this 10mm Shooting Dynamics cartridge.

This round is optimal for self-defense thanks to its 180 grain jacketed hollow point projectile. The bullet’s jacket wears little notches pressed around its tip, which serve to ensure that fast expansion occurs along a preset path for unerringly deadly terminal effect. The bullet’s strong and concentric jacket promotes proper penetration and rotational stability in flight, respectively, so its as trustworthy in a self-defense scenario as it is rewarding practice at the range. Fiocchi’s state of the industry manufacturing process yields great brass casings, Boxer primers, and fast burning propellant which are all front and center in this round.

This 10mm cartridge is from Fiocchi’s Shooting Dynamics line of ammunition. It’s loaded to closely emulate the recoil and in-flight performance of their analogous higher end Exacta load, but it’s priced to make self-defense and training more accessible to everyone.

This cartridge will quickly lay out virtually any threat you could conceive, and not simply because the 10mm is such a powerhouse. It features a 180 grain jacketed hollow point projectile, with nicks around its rim that provide preexisting fault lines along which expansion can reliably take place. This cartridge’s propellant charge consistently produces a supersonic muzzle velocity, so you can count on the kind of impact energy which makes ensuing expansion all the more catastrophic for its recipient.

Fiocchi implements high quality raw materials to make reliable primers and strong brass casings. This round’s casing begs to be handloaded once it has been emancipated from its contents the first time, so do scoop each one up after your pistol has spat it out!

PMC is one of the premier companies in high quality but inexpensive ammunition. Their integration philosophy insures some of the best quality control. With their supplier manufacturing all of their parts themselves, this gives rise to incredibly high quality control.

Manufactured to strict standards, this 50 round box of 10mm Auto PMC ammo is just what you need. Three years after the FBI disaster in Miami in 1986, the FBI adopted the 10mm Auto for a short time. In fact, some people still prefer this round over the round the FBI switched to after the 10mm Auto, the 40 S&W, referred to by some to as the 40 Short and Wimpy.

This powerful, 200 Grain round fires at 1050 fps, packing a huge punch. This 50 round box of FMJ-TC rounds are perfect for range training, keeping you in practice for when you need to stop someone with massive force. Don't miss out on this great deal and pick up some today!

Sure – you could hold up your empty handgun and say “pew pew pew,” but that’s not actually going to make you a better shooter. That’s your expert shooting tip for the day. Here’s another: For training at the range or otherwise enjoying your firearm however your please, Federal’s Champion line offers the perfect way to do so.

This 10mm cartridge features a 180 grain full metal jacket projectile. Its core is evenly distributed in weight, as is its jacket, which grants it great balance as it whirls away toward its target. This bullet’s jacket is hard enough to keep lead off of a handgun’s riflings without inadvertently filing them down, and even helps a semi-auto shift the cartridge from magazine to chamber more reliably. All in all, when you can do without terminal expansion, this is the bullet you want.

Federal is careful to only turn out brass that chambers precisely, and which possesses all the suppleness that clean ignition and the option to reload afterward demand. Their priming mixture doesn’t create caustic byproducts that could threaten your handgun with rust, and their clean burning propellant prevents the kind of residue accumulation that gradually chips away at a weapon’s accuracy in between cleanings. Tack on a box of these target practice rounds to your order and see why Federal has endured for 100 years to become one of America’s preeminent ammo makers.

This high-velocity 10mm Auto ammunition from PMC is a cost-effective choice for both target shooting and defense. Each case contains 500 cartridges.

Distinctive features of this ammo include a relatively light 170 grain jacketed hollow point bullet and a muzzle velocity of 1,200 feet per second. This combination gives the projectile better expansion potential without dramatically increasing recoil.

PMC ammo is loaded in South Korea using non-corrosive primers and reloadable brass. These components are made in-house for improved quality control.

Do you want to order just one type of 10mm ammunition that you can bank on for both range training and self-preservation? Federal Premium is way ahead of you! The old Minnesotan company’s Train + Protect line of ammunition makes it easy to prepare for target practice and self-defense alike!

This cartridge is loaded with Federal’s own Versatile bullet. The 180 grain jacketed hollow point has the balanced weight distribution and consistent profile that great accuracy depends upon. The Versatile bullet’s hollow point nose cavity is surrounded by a notched jacket. When impact forces the nose cavity to commence expansion, the jacket splits open to promote fast terminal ballistics that maximize energy transfer to surrounding soft tissues while simultaneously tracking a wide, debilitating wound channel.

Train + Protect ammunition is loaded with Federal’s most reliable noncorrosive Boxer primers – nothing else will do when your pistol becomes your only means of protection. Federal’s new production brass cases cycle precisely as they’re meant to, and they are reloadable as soon as their spent primers are extracted.

A full-power 10mm Auto load equally suited to target shooting and defense, this ammunition from PMC delivers excellent value for fans of this powerful cartridge. Each box contains 25 rounds.

This ammo fires a light 170 grain jacketed hollow point bullet at 1,200 feet per second, delivering excellent expansion potential without excessive recoil (though like all 10mm loads, it does have a substantial kick to it).

PMC ammunition is made in South Korea using internally sourced components including non-corrosive primers and reloadable brass cases.

Hornady’s American Gunner series ammunition is built for unerring dependability – exactly what you want from your 10mm self-defense ammunition (assuming you like going home in one piece every night).

The eXtreme Terminal Performance is a premium jacketed hollow point. Between its swaged lead core and superbly concentric jacket, it has all it needs to showcase great accuracy (the very reason why several shooters compete with it). The rim of the XTP’s jacket is surrounded by notches, and significantly thinner than it is at the base of the bullet. Both of these features work in favor of wider, more reliable expansion following lower-velocity impact. The XTP’s jacketed rim also helps it avoid catching on anything as it feeds, and prevents damage that might have caused the JHP to exhibit suboptimal expansion. Hornady thinks of everything!

This is by no means the lowest-recoil ammo you could select for defense. Its heavy striking power is well worth that fiercer kick, however, and its flat trajectory won’t prove disadvantageous if you have to clear any amount of distance between yourself and the threat.

Is Hornady Custom the answer to all of life’s problems? No. For example, this premium 10mm Auto ammo will not help you paint your house. But it does perfectly solve one very specific problem: “How do you defend yourself using only a 10mm firearm?”

This round’s 155 grain bullet presents a huge problem to anyone who attempts to violently end your existence. The eXtreme Terminal Performance, or XTP (Hornady took a little creative license with that acronym, admittedly, but they’ve earned that right) serves up excellent accuracy. Its jacketed rim doesn’t get dented by the feed ramp, so it remains aerodynamic while it’s being chambered. Its swaged lead core and copper-alloy jacket are both balanced, which gives the XTP excellent in-flight stability.

The XTP also produces highly reliable terminal expansion. Its jacket is drawn instead of plated, which is why it is thick around its base and thin around its rim. Its jacket is also divided into symmetrical sections by a series of precision cut serrations. Together, these features enable the XTP to expand at a uniform rate and to a wide diameter under a wide range of conditions.

Count on this ammo’s matched primer/powder pairs to supply a steady 1,410 fps muzzle velocity out of a 5” barrel. That translates to well over 600 ft lbs of striking energy at close range. Each Custom load also features the highest-quality reloadable brass case Hornady could manufacture or source.

Boars got tusks. Bears got claws. Moose got hooves. Catamounts got teeth. And what do you got? That’s right: a 10mm Auto handgun. And thanks to Underwood of Illinois, you can now have the best ammo for defense against dangerous creatures, too.

This round’s 200 grain hard cast bullet features a Black Cherry polymer coating. The self-lubricating coating reduces friction against the bore, and it eliminates lead fouling while it’s at it. The bullet’s nose profile is flat instead of round: not just because it is a 10mm bullet, but because it is designed to inflict as much damage as possible without undergoing terminal expansion.

The hard cast bullet doesn’t expand by design. It hardly deforms at all, in fact, which is why it applies as much of its energy as possible toward one single goal: deep penetration. The bullet would most certainly pass through a human-sized threat. But when you’re fending off a large animal, a bullet that crashes through hide, fat, sinew, muscle and bone is ideal.

This ammo’s low-flash propellant is just the stuff if you’re caught by a critter at night. It’ll help you continue seeing your target after firing your first shot. Nickel-plated brass cases are a hallmark of high-quality ammo. They ward off corrosion. They reduce metal-on-steel friction. They even reflect more light, and are accordingly easier to spy in the chamber.

For a fast-moving, hard-hitting 10mm Auto carry load, try this ammunition from Hornady. These cartridges fire the XTP jacketed hollow point bullet, which is known for its strong penetration.

Each round in this box of 20 fires a 155 grain jacketed hollow point bullet at a muzzle velocity of 1,410 feet per second. Compared to other 10mm loads, these rounds fire a relatively light bullet at a high velocity--a combination that helps produce better expansion.

Hornady ammo is loaded in Grand Island, Nebraska using non-corrosive primers and reloadable brass cases.

A 10mm pistol is an indisputably effective tool for self-defense. But a cartridge that’s designed to neutralize a human threat isn’t necessarily sufficient for bears or wild hogs. If you’re concerned about what either of those critters could do to your body, then Underwood makes the perfect ammo to defend it with!

This cartridge’s 220 grain projectile is a hard cast: high-antimony lead, which is too tough to expand, flatten out or otherwise become deformed as it tunnels its way through a dense mass. A hard cast is accordingly capable of delivering a wound channel which extends all the way to a bear’s beating heart – which it won’t be, for much longer. Underwood’s hard cast bullet is completely enveloped in Black Cherry polymer, which prevents the alloyed lead from abrading the surface of the bore and eliminates lead fouling!

Trust Underwood’s flash-suppressed powder not to blind you if you ever have to fire at dusk or night. Count on their nickel-plated brass cases to safeguard your beast defense loads against corrosion. Look forward to smooth operation courtesy of the American manufacturer’s tried-and-true loading practices!

After Frontier Ammunition became Hornady Custom in 1983, Hornady's business took off and Hornady became a leader in the world of ammunition. With decades of trusted ammunition manufacturing, you know you can trust Hornady with your ammo needs.

The 10mm Auto is a fantastic round that packs a pretty big punch. In fact, it was employed for this reason by the FBI after the disaster in Miami in 1986. However, it has quite a large recoil, which later lead to its decommission. That said, this is not a good round for lighter people, although stronger people may feel the force behind this powerful round.

The Hornady designed XTP, or Extreme Terminal Performance, was created to deliver massive stopping power and expansion upon impact. With these 180 grain, 10mm Auto, JHP XTP rounds in your pistol, you will deliver all the stopping power you need. Pick up a 200 round ammo can today!

It can be fun to add extra challenge to the way you hunt. Ask any bow hunter and they’ll agree. But if you’ve chosen to claim your next trophy with a 10mm Auto lever-action rifle – a powerful thing in its own right, but not when it is compared to most other lever guns – there’s no sense in selecting anything less than the best ammo for the task at hand.

Coincidentally, we’re selling it: Hornady LEVERevolution, which is loaded with special polymer-tipped bullets that maximize every aspect of performance. The key to the FTX’s jaw-dropping accuracy is its Flex Tip, which minimizes frontal drag to promote flatter trajectory and more authoritative striking energy. Impact squashes the supple Flex Tip, at which instant it forces wider expansion than a JHP would likely accomplish at the same velocity. The FTX’s InterLock ring, which nestles an extension of its copper-alloy jacket inside its lead core, makes the bullet durable enough to withstand high-velocity impact with the momentum it needs to continue tunneling deeply into its target.

Worried about accidental discharge in the magazine? There’s no need. The Flex Tip is sturdy enough to survive ignition undeformed, yet also soft enough that it can’t ignite the primer it rests against in the mag.

Although initially designed by Jeff Cooper in the United States, the 10mm Auto was first mass produced in Sweden. After the 1986 disaster in Miami, the FBI used it as their official pistol round, although it was later decommissioned. These 180 grain 10mm Auto rounds are reliable and accurate, although with such a large recoil, it is not ideal for smaller people.

With Hornady's eXtreme Terminal Performance ammo, or XTP, you will not be disappointed. This jacketed hollow point ammo is specifically engineered to have fantastic terminal expansion, you cannot go wrong. Hornady is a trusted manufacturer throughout America, and with their specialty XTP 10mm Auto rounds, you know you have some of the best self defense rounds in your firearm.

No one buys a 10mm pistol hoping they will one day need to use it. That said, no one buys a 10mm pistol with the assumption that they’d never have to rely on it for self-defense, either. That’s why you need Speer Gold Dot 10mm ammunition. You hope you’ll never need it, but you’ll sure be glad you have it if you do!

This cartridge’s 200 grain jacketed hollow point is Speer’s own Gold Dot. It features a concentric bonded jacket that helps the bullet stay stable in flight until it reaches a barrier, at which point it keeps the bullet from shedding too much weight to enter deeply into the threat. The Gold Dot’s nose cavity is carefully engineered to let loose fast, wide and highly injurious terminal expansion. The bullet’s 1,100 fps muzzle velocity out of a 5” barrel also ensures that it will reach 100 yards with over 400 ft lbs of kinetic energy, which will create the desired effect instantly with correct shot placement.

This ammo is designed to withstand exposure to the elements. Its sealed Boxer primers and corrosion-resistant nickel-plated brass cases both attest to that fact. Nickel also minimizes friction to promote surer functionality in a semi-automatic!

Don’t get caught off guard by a perilous altercation. Be ready, with Winchester USA Ready Defense!
Winchester loads this 10mm ammo to lot-controlled perfection. Each round sparks up without error thanks to its match-grade primer. Each round reliably propels its 170 grain bullet to a muzzle velocity of 1,250 fps (5” test barrel), so you’ll rightly anticipate recoil and point of aim. Each round also features a plated brass case: nickel, which is more resistant to corrosion and jamming than plain brass.
When a jacketed hollow point strikes clothing, drywall, or any other light barrier that might come between the muzzle and the threat, its nose cavity risks clogging up with debris. Winchester’s Hex-Vent solves that issue. When the rigid polymer component encounters a barrier, it keeps debris from ramming into the nose cavity. But when it hits soft tissue, the Hex-Vent does nothing to impede its passage into the nose cavity, in which it pressurizes to force wide outward expansion.

Wait a minute. Isn’t Hornady’s Critical Duty series ammunition intended for sale to law enforcement officers? That’s correct. But it’s not exclusively sold to LEOs, which is why you’re able to chamber the very best 10mm self-defense ammo ever to come out of the great state of Nebraska.

This round’s FlexLock jacketed hollow point bullet’s 1,160 fps muzzle velocity was recorded with a 5” test barrel. Pretty standard stuff for a 175 grain 10mm bullet. It’s what’s inside the FlexLock that makes it so special:
• A Flex Tip, which preserves the nose cavity’s ability to trigger terminal expansion by preventing it from clogging up with debris • An InterLock band, which mechanically locks the core and jacket together so as to prevent the two from separating; more economical than bonding, yet similarly effective

The FlexLock is seated in a nickel-plated brass case. It looks nice, but its actual purpose is twofold:
• Prevention of tarnishing that could impair cycling in a semi-auto
• Reduction of friction that could do the same

This ammo additionally features flash-suppressed propellant. It keeps your eyesight acclimated to a dark environment, which you’re certain to appreciate if you intend to aim at whichever threat you wish to neutralize.

This defensive ammunition from Hornady's Critical Duty combines the high caliber and power of the 10mm Auto with the wide expansion and deadly terminal ballistics of the Flexlock hollow point bullet. Each cartridge in this box of 20 fires a 175 grain projectile at a muzzle velocity of 1,160 feet per second.

The Flexlock bullet is distinguished by its soft polymer tip, which controls expansion for optimal performance and keeps barriers such as thick clothing, glass, or sheet metal (which this ammo is designed to penetrate without losing its effectiveness) from clogging the projectile's cavity.

Hornady ammunition is loaded in Grand Island, Nebraska and uses non-corrosive Boxer primers and nickel-plated brass cases.

Winchester developed their Defender line of ammunition to put police grade performance in the hands of the regular civilian. If you would like 10mm ammunition that meets the performance criteria set forth by the FBI test protocol, you’re looking right at it.

This round of ammunition is loaded with a 180 grain bonded jacketed hollow point. Its core and jacket are welded together, which preempts the core/jacket separation that leads to fragmentation and resultant shallow penetration. The jacketed nose cavity is notched on the inside and out. As penetration pressurizes the nose cavity’s interior, it fans out eight pointed petals that inflict accented damage to surrounding soft tissue. The precision-notched JHP consistently mushrooms up to 0.6 inches in diameter.

Nickel-plated brass cases aren’t just reloadable. They are easier to see in a dark chamber because they are shinier, easier to cycle through a semi-auto because they reduce metal-on-metal friction, and corrosion resistant. This ammunition also features low-flash propellant, which preserves your ability to see the target while you’re firing in low lighting.

This 10mm cartridge by Federal features a 200 grain HST projectile that tackles barriers to deliver devastating expansion in its target. The bullet’s hollow point nose cavity resists becoming plugged up with fabric and other debris that could impact its ability to initiate expansion, and its core and jacket are united via cannelure to ensure they retain the weight requisite for deep penetration. The skives in the HST’s jacket strategically weaken it to ensure that it can reliably expand into a star shape. This promotes a simply lethal wound channel, but also one that won’t overextend to put innocent bystanders in harm’s way.

This cartridge provides a nickel plated brass casing which feeds into and extracts from a semi-automatic weapon like clockwork. Its bullet’s streamlined profile and responsive Boxer primer do their parts to promote flawless cycling as well, so you can count on the round to deliver when you’re in a tight spot.
