Testing The Army's 7.62mm Wonder Bullet: M80A1 reduced velocity gel test
This video details a reduced velocity gel test of the Army's M80A1 7.62mm bullet, fired from a 300 Blackout case using an 8-inch AR-15 upper. Despite the lower velocity (around 1700 FPS), the M80A1 demonstrated significant fragmentation and created a substantial temporary stretch cavity, with the penetrator exiting at 14.2 inches. The instructor notes this performance is excellent for rifle bullets at such speeds and anticipates similar testing for the Mk 319.
