These 50 rounds, manufactured by Black Hills, contain a 77 grain Sierra MatchKing open tip match bullet that flies through the air with the accuracy and precision you expect from professional grade ammunition. This civilian load is almost identical to the U.S. military's MK262 Mod 1 round, but with a minor difference in the primer and powder. Developed by Blackhills Ammunition, along with the US Army and US Navy, this round offers increased accuracy and lethality. The advertised muzzle velocity of this ammo is 2,750 feet per second, with a muzzle energy of 1,293 foot pounds of force. These rounds are Boxer-primed, brass cased, reloadable and non-corrosive.

Black Hills Ammunition was founded over 30 years ago. They supply match-grade 5.56 ammo for the U.S. Military's Service Rifle Teams, as well as other specialty ammunition for various military operations. They also provide Cowboy ammunition in more calibers than any other ammo company.

Q: What is the G1 ballistic coefficient of the Black Hills 77g OTM bullet?

Posted On: 12/14/2018 By: Russ

A: According to the Shooters Calculator.com the ballistic coefficient of the 5.56x45 77gr OTM is 0.362. Now this will be according to your conditions. I hope this helps. Thanks

Q: I have checked several ballistic calculators, all of which indicated this load should preform well in 1:8 twist barrels; however, I’d appreciate Lucky Gunner’s opinion. Thanks,!

Posted On: 7/4/2018 By: Roy Kiefer

A: Hi Roy, A 1:8 twist barrel will do best with a grain weight between 62 and 77 grain. It can use weights as low as 40 grain or as high as 87 grain with a slight reduction in accuracy. It is not recommended to go lower or higher than this range as performance will suffer.

Q: What exactly is the difference between the military version vs the civilian version?

Posted On: 4/24/2018 By: Jeremy

A: Hi Jeremy, The civilian version, such as this one, will typically have more polishing and finishing done to the rounds. The military version was made for military use and the military puts more emphasis on function over aesthetics.
