223 (5.56) Ammo

.223 Remington ammunition and 5.56x45 NATO are closely related and sometimes interchangeable cartridges depending on the firearm they are to be used with. Manufacturers typically offer guidance on this point. In general, the 5.56 NATO ammunition the military uses and is for sale to the civilian market operates at higher pressures than .223 Remington ammo. Most, but not all, AR-15s are chambered for 5.56 NATO and can fire both types of ammo.

Many loads in both calibers follow the M193 or M855 standard, both of which are military specifications. M193 ammo typically fires a 55 grain full metal jacket bullet at 3,240 feet per second, while M855 ammo fires a heavier 62 grain FMJ bullet at about 3,100 feet per second. These common standards are very helpful when sighting in your optics and you'll find both cartridges in-stock and available in cheap bulk packs here at Widener's

Certain specialized loads deviate from these common standards. Competition grade .223/5.56 ammo fires a heavier bullet (most commonly a Sierra MatchKing) in the 77 grain range to provide better stability and more predictable trajectories; varmint loads, on the other hand, fire light 30-40 grain bullets at very high velocities to produce lethal fragmentation against pest animals.

One of the most sought after range loads for this caliber is Lake City ammunition, which is produced by Federal Premium Ammunition at the Lake City Army Ammunition Plant in Independence, Missouri. LCAAP production is typically excess from government contracts and is popular due to its military origins and high quality.

    A short-barreled rifle (SBR) is an excellent tool for personal defense. But if your barrel measures between 10.5” and 11.5”, then you would be well advised to select ammo which is specially intended for it.

    Hornady’s BLACK series 5.56x45 ammo is loaded with the 75 grain InterLock HD SBR. It excels at initiating expansion flowing low-velocity impact courtesy of its exposed supple lead tip and grooved, tapered jacket. It also has the durability it needs to defeat a wide variety of common barriers thanks to its cannelure and InterLock ring, which doubly anchor its jacket and core together. Hornady designed the InterLock HD SBR to excel at the FBI test protocol for self-defense ammo. They succeeded.

    This ammo’s powder is similarly engineered to supply optimal functionality in SBRs. It minimizes blinding muzzle flash, softens report to an impressive degree, produces extremely little fouling, and does not overheat a suppressor. Hornady’s best brass cases feed without hesitation, and their Boxer primers are intensely reliable.

    Hornady also recommends this ammo for medium game. A great choice for a midnight boar bonanza!

    This 200-round case of 5.56mm NATO ammunition is a great purchase for competitive match use or for testing out a new high-class build from Desert Tech or LaRue Tactical. Each round utilizes a 75-grain hollow point boat tail (HPBT) projectile which exhibits superb accuracy due to its measured internal balance, consistent outer dimensions, and aerodynamic shape. In addition, a toothed cannelure keeps the heavyweight bullet firmly seated within its crimp so that recoil vibrations don't upset final shot placement.

    The reloadable brass casing of each cartridge is filled with a potent charge with powder, like all Superformance rounds, which produces breathtaking muzzle velocity for flatter shooting out to greater distances. This propellant accepts a spark from a non-corrosive Boxer primer which is accompanied by sealant that prevents moisture from ruining its ignition quality. Hornady's projectiles and finished ammo are supported by expertise that dates back all the way to 1949.

    Are you looking for the right round to stick into the AR-15 you keep handy for personal protection? Then look no further -- this 223 Rem cartridge from Hornady’s Critical Defense line of ammunition is host to several features that will work hard to keep you safe.

    This round is crowned with Hornady’s own 73 grain FTX. The bullet’s Flex Tip shields its nose cavity from jamming up with detritus like fabric or drywall that would inhibit its ability to cause expansion. That tip is also soft and extends into the underlying high antimony core, so it wedges downward upon impact to trigger massive expansion. The FTX boasts the ability to penetrate deeply, as its InterLock ring secures its core to its jacket, and this FTX is furthermore exceptionally heavy. A ballistically efficient secant ogive profile makes the FTX fly straight toward its target as well.

    This round’s propellant is carefully weighted to ensure a reliable muzzle velocity, and is furthermore treated to lessen muzzle flash.

    Do you want to stamp true cloverleafs into your target? Then you’d better fire ammunition that was made for the job! Remington loads this 223 Rem cartridge with Sierra’s 77 grain MatchKing so you can squeeze the best accuracy out of your rifle yet!

    The MatchKing is an extremely high-quality hollow point boat tail projectile. Unlike a pistol cartridge’s JHP, the BTHP’s nose cavity is not meant to deliver terminal expansion inside game. Instead it allowed Sierra to pour liquid lead into the MatchKing’s thin and concentric jacket, thus creating a uniform and flawless core. Together the MatchKing’s ballistic jacket profile and boat tail both minimize drag to the greatest extent possible. Its exceptionally heavy 77 grain weight also helps the MatchKing to retain momentum which prevents gentle breezes from blowing it very far off of its intended trajectory.

    Remington’s highest-quality brass case and match primer tie the whole package together. So long as you’re using the recommended 1:6", 1:7" or 1:8" rate of twist for a 77 grain projectile, you can expect this ammo’s flat trajectories to retain supersonic velocity well past the 800-yard line!

    This 223 Rem cartridge from Hornady’s Critical Defense line of ammunition is optimized in every way to help you keep your home uninfluenced by burglars. The round’s 55 grain FTX projectile features the Flex Tip, which compresses into the bullet upon impact in order to initiate rapid expansion. The Flex Tip works reliably even at lower velocities, and optimizes performance in lever action rifles as well.

    The FTX bullet also features an InterLock ring, which mechanically locks its high antimony lead core and specially engineered heavy jacket together to provide stellar weight retention during penetration. This bullet additionally offers a flat trajectory and great accuracy thanks to its secant ogive profile.

    This round’s specially formulated propellant reduces both recoil and muzzle flash, so you can count on firing rapid follow-up shots in the dark as well.

    Each round in this box of 50 fires a 69 grain open tipped match bullet at 2,875 feet per second. The use of a relatively heavy bullet provides more stable and predictable trajectories for your shots at the cost of some muzzle velocity; since terminal ballistics is irrelevant for match use, this trade-off is a no-brainer!

    Black Hills ammo is loaded in Rapid City, South Dakota using reloadable brass and non-corrosive primers.

    This 223 Rem cartridge from Hornady’s Critical Defense line of ammunition features a 73 grain FTX projectile. The heavy FTX is able to penetrate deeply, and is prevented from shedding very much of its weight during penetration by its InterLock ring. The FTX’s secant ogive profile grants it the ballistic coefficient needed for accuracy at longer ranges. The FTX’s Flex Tip reliably initiates powerful expansion even at lower velocities, and additionally serves to protect the hollow point from clogging with fabric and other media.

    If you ever have to engage a threat in the nighttime, you’ll appreciate how this round’s low-flash propellant emits little light when ignited, protecting your vision so you can continue firing accurately.
    This ammunition was previously loaded with nickel-plated brass cases. It no longer is.

    You’ve built yourself a beautiful 5.56x45 MSR, replete with every bell and whistle under the sun. But without beautiful 5.56x45 ammo, that MSR’s accuracy won’t amount to a hill of beans. What are you going to do about it? Give up your favorite hobby? Not bloody likely. You’re going to order yourself a whole case of 5.56 match ammo by Black Hills – the same company that delivers the good to U.S. military sniper teams!

    Sierra’s MatchKing projectile features a thin and concentric jacket, a uniformly distributed solid lead core, and a sleek jacket profile. The Missouri company’s MatchKing Tipped has all of that plus a ballistically efficient acetyl resin tip, as well as an ogive that is even further optimized to curtail in-flight drag. This round’s projectile is also a heavy boy at 77 grains, which helps it conserve more of the momentum it needs in order to thumb its nose at cross and vertical winds. The TMK is solely designed for long-range accuracy; if you expect it to expand after impact, it will fail to satisfy your expectations.

    Every round in this 10-box case of ammo is loaded with a reusable brass case, match Boxer primer, and propellant charge that produces a very reliable ~2,750 fps muzzle velocity in conjunction with a 20” barrel.

    Customer Reviews

    You’re not messing around. You’re going to prove that “effective range” is merely a concept by covering insane distances with your 223 Rem rifle – and Hornady Superformance is precisely the 223 Rem ammo you need to do it!

    This cartridge is loaded with a big boy 75 grain projectile. That extra mass equals greater inertia, ergo higher resistance to wind deflection hundreds of yards downrange. As a hollow point boat tail, the bullet possesses the form-fitted lead core it needs to exhibit formidable rotational stability and the tapered base that helps to conserve momentum.

    Whereas your run of the mill 223 round’s 55gr FMJ achieves a G1 ballistic coefficient of 0.243, this round’s tack driver of a 75gr HPBT has a G1 BC of 0.395. In other words, its trajectory will peak at about 5.23” before it reaches a 300-yard bullseye (assuming your rifle has a 24” barrel, which is the test barrel length Hornady used to record this round’s 2,930 fps muzzle velocity, and your sights are set 1.5” high).

    Hornady’s Superformance Match series ammo achieves a muzzle velocity that’s about 200 fps higher – without producing more unwanted recoil, muzzle blast, fouling or chamber pressure in the process. This ammo hails from Nebraska, where Hornady loaded it with their highest-quality reloadable brass cases and primers.

    Please note: Despite its appearance, the HPBT will not deliver terminal expansion. It is solely designed for accuracy.

Tipped MatchKings are an iteration building on the classic MatchKing bullet and feature an aerodynamic polymer tip.

    When the U.S. military needs match grade 5.56x45 ammunition, it turns to Black Hills Ammunition. It’s no coincidence that the family-owned South Dakota company also produces some of the finest long-range target ammunition the civilian market has to offer. Order yourself some today and start shooting faraway targets soon!

    This cartridge gives you accuracy like only a 77 grain open tip match bullet can. The huge chunk of lead and copper has a lower muzzle velocity – 2,750 fps out of Black Hills’ own 20” test barrel – but also a trajectory that’s less susceptible to wind deflection. The OTM’s form-fitted core was created by injecting the thin copper jacket with molten lead. The hollow point gave access to that lead, but it does not give the OTM the ability to deliver terminal expansion.

    Black Hills loads this ammo with match primers, match brass, and standardized charges of proprietary propellant blend. Despite what the discoloration around their shoulders might suggest, this ammo’s cases aren’t previously fired. They’re a great choice for handloading – might as well stock up on component bullets while you’re at it!

    You’ve got two things on your mind: precision, and your 5.56x45mm rifle. That means you only need one kind of ammunition: this 77 grain OTM ammo by Black Hills of South Dakota.

    Let’s get one thing straight: the open tip match may look like it’s designed for terminal expansion, but it really isn’t. If you’re looking for hunting or home defense ammo, then your journey continues. The OTM’s open tip has already served its only purpose, which was to allow its manufacturer to inject liquid lead into its thin and concentric copper jacket. The voidless core that formed is the driving force behind the OTM’s excellent rotational stability and resultant high accuracy.

    This round’s bullet is relatively heavy, which helps reduce its reaction to the cross and vertical winds awaiting at a long-distance target range. A 1:8” rate of twist barrel or faster is the ticket. Black Hills loads these fine rounds with match grade components, as well as brand new reloadable brass cases.

    THE SDM Ammo for taking out the trash

    This is the MK262 MOD 1 ammo used by Uncle Sam's DM's for use in 1:8" twist or faster barrels, with 556 NATO or 223 Wylde chambers. I tested a single 5-shot group from a bipod at 600yds and the elevation was a tick over 1/2MOA from a sample rifle used to train soldiers at Ft Benning.. Close enough for gov't work.

    Review by Grant (Posted on 2/19/2022)

    You get what you pay for.

    Three five shot groups, each under .750 inches at 100 yards. Best ever from my Colt LE 6920. Let the barrel cool between groups.

    Invented in the 1960's during the Vietnam War, the 223 Rem was designed to give soldiers and civilians the lightweight, low recoil, incredibly accurate, high speed round they need for all their shooting purposes.

Firing at 3240 feet per second, those varmints won't stand a chance against this high quality Winchester ammo.

    Among initiated hunters and precision shooters, the Barnes name is credited for some of the most precise components and ammunition in existence. By that note, these heavyweight 5.56x45mm cartridges from the VOR-TX can be trusted for varmint hunting, short-range conquests on big game, and even personal protection purposes. Each round is loaded with a 70-grain TSX projectile which has a one-piece body completely made up of gilding metal with a tiny hollow point up front. During entry into game, the TSX is designed to expand and double its diameter with a petaled pattern, slicing its way through dense hide and meat while tumbling and throwing momentum into vital areas.

    In addition, the projectile's banded body improves gas trapping and facilitates incredible balance for tight accuracy downrange. The TSX bullet is crimped into a reloadable brass casing which has been checked over for burrs and inconsistencies. A non-corrosive Boxer primer is triple-staked into the casing's base pocket in order to prevent primer popping, potentially a rifle-killing malfunction, from occurring. Due to the increased pressure and heavy bullet weight of this 5.56mm NATO ammo, Barnes suggests that the round should only be fired through barrels with 1:8 or faster twist rate and never be used in .223 Remington chambers.

    Barnes is highly regarded for the quality of their solid copper bullets – but the old Utahan company certainly knows how to make a great traditional lead-core bullet as well. For proof of that you need look no further than this Precision Match series 5.56x45 ammunition, which features the Match Burner open tip match boat tail projectile!

    This round’s OTM BT is a big boy at 69 grains. It’ll supply you with a lower muzzle velocity of 2,900 fps, but that pays off in the form of superior downrange momentum – precisely the property which gives a bullet greater immunity to wind drift. The OTM BT’s match jacket, tapered tail, form-fitted lead core and hypodermic needle-like tip give the bullet the balance and sleek profile it requires to exhibit a 0.330 ballistic coefficient. That translates to 300-yard trajectory which pinnacles at 6.4”, as well as supersonic velocity until approximately 850 yards.

    You may already know this, but the OTM BT is unsuitable for hunting game larger than varmints. The bullet may technically have a nose cavity, although that feature is not designed to initiate terminal expansion at any velocity. As such the OTM BT’s terminal ballistics are pretty much identical to an FMJ’s.

    Match-grade primers, expertly loaded propellant and top-end reloadable brass cases complete Barnes’ awesomely accurate Match Burner bullets. Order a box or five and prepare to witness your 5.56 rifle’s true potential!

    If you've set up your AR-15 for defense or varmint hunting, you can make good use of this .223 Remington ammunition from Black Hills. These cartridges fire the Barnes TSX hollow point bullet, which delivers rapid fragmentation and highly effective performance against coyotes and other pest animals.

    Each round in this box of 50 fires a 62 grain version of the TSX at about 3,100 feet per second, producing similar external ballistics to M855 ball ammo. This is a valuable trait, since it means you can fire range loads and hunt without adjusting your optics before either activity.

    Black Hills is a high end ammo manufacturer and defense contractor based in Rapid City, South Dakota. Their products use non-corrosive Boxer primers and reloadable brass cases.

    A versatile load suited for defense and hunting applications, this 5.56 NATO ammunition from Black Hills is the perfect choice for multipurpose AR-15s and other .223/5.56 rifles.

    Each round in this box of 50 fires a 62 grain Barnes TSX hollow point bullet at 3,000 feet per second. The TSX is a solid copper design with a grooved shank that absorbs expanding bullet material to reduce fouling and chamber pressures. It delivers very strong expansion, a key benefit in this relatively low-caliber cartridge. External ballistics of this load are comparable to (and somewhat more consistent than) those of M855 ball.

    Black Hills is a renowned supplier of defensive and sporting ammo and counts all branches of the US military among its customers. Their products are made in Rapid City, South Dakota using non-corrosive primers and re-loadable brass.

    The Blackhills 62gr TSX performs!

    I was told this by Ozzy from (BHA), The Blackhills local Sniper and SWAT teams conducted numerous tests through windshields and doors with this TSX 62rg round and confirmed the performance. Also the local response teams and agencies have chosen the 62gr TSX as their issued duty load because of its performance. The 62 TSX performs the same as the 50gr TSX as far as performance through barriers and retaining the petals, according to Ozzy from Blackhills, hope this info helps you guys.
