223 (5.56) Ammo

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.

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.

Competitive shooters of AR-15s and other 5.56 NATO rifles prize Black Hills match grade ammunition for its unerring precision and reliable performance.

Each round in this box of 50 fires a heavy 77 grain Sierra Tipped MatchKing bullet at a muzzle velocity of 2,750 feet per second. As with most match loads, this ammo trades a bit of muzzle velocity for enhanced stability and more predictable points of impact. Tipped MatchKings are an iteration building on the classic MatchKing bullet and feature an aerodynamic polymer tip.

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

Barnes Precision Match ammunition is here to treat you to some of the best accuracy you’ve ever witnessed! This 223 Rem cartridge features the Match Burner – a 77 grain open tip match boat tail projectile that is designed for competitive shooting events!

First things first: an OTM bullet is not intended for hunting or home defense, simply because its hollow point nose cavity isn’t engineered for terminal expansion. The OTM’s meplat has a narrow aperture because liquid lead was poured through it – hence the bullet’s voidless, balanced, and rearward-situated core. The bullet’s narrow tip, tapered tail, and sleek, thin jacket are all in the service of minimizing drag, increasing downrange momentum, and enhancing precision. Its massive 77 grain weight gives the bullet greater resistance to wind drift as well (Barnes recommends a barrel twist of 1:8” or faster for this ammo).

This round has a G1 ballistic coefficient of 0.349. Many variables will determine exactly which trajectory the bullet follows, but you can realistically expect around -9.57” drop at 300 yards when you set your rifle’s 1.5” high sights on a 200-yard zero.

Barnes loads this ammo in Utah with match primers, fastidiously measured propellant charges, and new brass cases that belong at a reloading press once they have been emancipated from their bullets.

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.
