Black Hills
produces factory new rifle ammunition equal to some of the best handloads. It is quickly becoming one of most popular manufacturers of ammunition. Used primarily by all branches of the United State military, this ammunition is also used by competitive shooters and hunters.

Black Hills has again expanded its popular line of 5.56mm ammunition. Sierra 77 grain MatchKing™ bullets set the standard for long range accuracy in .223 and 5.56. World records have been set with those bullets, and MK262 ammunition loaded by Black Hills using MatchKing™ bullets has provided significantly increased capability to our nation's soldiers, sailors and Marines. Sierra has now further refined this bullet with the addition of a polymer tip which improves upon the external ballistics by significantly increasing ballistic coefficient from .373 to .420. What this means is that the new TMK projectile will be much more resistant to both drag and wind, meaning it will fly flatter and straighter in adverse conditions.The tip also improves terminal ballistics, increasing uniformity of performance and penetration when the projectile arrives on target. This new Tipped MatchKing™ is now offered as an additional Black Hills 5.56 load.

This ammunition is loaded with Lake City brass that has undergone factory annealing which extends brass life. As a result of the annealing process the neck portion of the brass may be discolored until the case is cleaned.

Please Note: While the 5.56x45mm NATO will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington chamber.
