Do you want to witness the pinnacle of MSR precision? So long as your rifle’s barrel has a 1:8” rate of twist or faster, you can! All you have to do is chamber up this HSM Match ammunition, which is similar (albeit not identical) to the 5.56 MK262 U.S. Armed Forces Service Rifle Teams utilize in the field.

This cartridge is loaded with a heavy, wind-resistant, and extremely aerodynamic Sierra MatchKing. It is an intensively uniform hollow point boat tail, with a jacket concentricity standard of ±0.0003”, and a weight standard of ±0.03 grains. It also wears the MK262 HPBT’s signature cannelure, which keeps seating depth optimal while recoil bucks the round around in the magazine. (0.372 G1/0.182 G7 BC)

Whether you use this ammo’s thinly jacketed non-expanding bullets for hunting small game – or merely use them to show off just what you can do with your rifle – you can count on HSM’s most meticulous loading protocol and highest-quality components to get you there.
