Civilian Ammo vs Military Ammo, Is There A Difference?!
This review compares civilian Black Hills 77gr OTM and military Mk 262 Mod 1 5.56mm ammunition. While visually similar, the military round features non-staked primers and consistently shows higher velocities (around 2675 fps vs 2659 fps). Terminal performance tests in watermelons and ballistic gel indicate the Mk 262 Mod 1 offers slightly more dramatic energy transfer and a larger wound cavity, suggesting it is functionally more powerful.
