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.

Hornady Superformance Match 5.56x45mm 75 Grain HP-BT - 20 Rounds
$27.75Product Type Ammo Manufacturer Hornady Condition New Bullet Weight 75 Grain Bullet Type Hollow-Point Boat Tail (HP-BT) Use Type match or precision shooting, plinking at the range, varmint hunting Casing Type Brass Quantity 20 Ammo Caliber 5.56x45mm Manufacturer SKU 81264 Primer Type Boxer Magnetic No UPC Barcode 90255812640 Cost Per Round $1.39 per round These heavyweight 5.56x45mm loads stretch the limits of their caliber thanks to Hornady's Superformance Match standards. In general, Superformance loads utilize unique propellant blends to achieve muzzle velocities that are well beyond the norm; that's why these rounds launch 75-grain BTHP projectiles at 2,910 feet-per-second from a 20-inch barrel, lending them amazing range capability for match use or long-range shooting in general.
The powder is contained within a reloadable brass casing which has a small amount of moisture-sealant in its primer pocket along with a Boxer primer; this arrangement guarantees reliable ignition under any conditions. The 75-grain BTHP at the top of the cartridge has a boat tail rear, tapered ogive, and tiny hollow tip for drag resistance which contributes to smaller groups. The bullet is built by feeding lead through the bullet's hollow point in order to build a dense core free of distortion while leaving the copper AMP jacket's pristine dimensions untouched.

Hornady Critical Defense 223 Rem 55 Grain FTX – 20 Rounds
$28.85Product Type Ammo Manufacturer Hornady Condition New Bullet Weight 55 Grain Bullet Type Flex-Tip-Technology (FTX) Use Type home defense Casing Type Nickel-Plated Brass Quantity 20 Ammo Caliber 223 Remington Manufacturer SKU 80270 Primer Type Boxer Magnetic No UPC Barcode 90255802702 Cost Per Round $1.44 per round 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.
Thanks to this round’s casing’s nickel plating, it’s very easy to spot during a chamber check in a darkened environment. Furthermore, its specially formulated propellant reduces both recoil and muzzle flash, so you can count on firing rapid follow-up shots in the dark as well. -
Black Hills Barnes Multi-Purpose Green 223 Rem 55 Grain HP - 50 Rounds
$72.85Product Type Ammo Manufacturer Black Hills Ammunition Condition New Bullet Weight 55 Grain Bullet Type Frangible Use Type steel target plinking Casing Type Brass Quantity 50 Ammo Caliber 223 Remington Manufacturer SKU M223N16 Primer Type Boxer Magnetic No UPC Barcode 612710124503 Cost Per Round $1.46 per round Grab a few of these 50-round boxes of .223 Remington ammo from Black Hills for tactical training and home defense with your AR-15 or other .223/5.56 NATO chambered rifle. These cartridges fire Barnes Multi Purpose Green (MPG) frangible bullets. Unlike other frangible projectiles, Multi Purpose Green bullets have a gilding metal jacket that protects the powdered copper-tin core. This ensures reliable cycling alongside heavy fragmentation upon impact. The fragmenting effect virtually eliminates the risk of ricochets for safe training while delivering strong terminal performance for varmint hunting or self-defense emergencies.
Each cartridge in this box fires a 55-grain version of the MPG at a muzzle velocity of 3,150 feet per second. In terms of external ballistics, this ammo is roughly comparable to M193 mil-spec ball and should not require large adjustments to optics for users of either M193 or M855 ammo.
Black Hills ammunition is made in the USA using non-corrosive primers and brass cases.

Black Hills Ammunition 5.56 NATO 62 Grain Barnes TSX HP - 50 Rounds
$99.85Product Type Ammo Manufacturer Black Hills Ammunition Condition New Bullet Weight 62 Grain Bullet Type TSX Use Type home defense, hunting boar, hunting whitetail deer, varmint hunting Casing Type Brass Quantity 50 Ammo Caliber 5.56x45mm Manufacturer SKU D556N18 Primer Type Boxer Magnetic No UPC Barcode 612710129621 Cost Per Round $2 per round 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.
