This video conducts a reduced velocity gel test comparing the Marine Corps' MK318 ammunition against the Army's M855A1. Both rounds are fired from a 10.5-inch AR-15 upper using a reduced charge of RL-15. The MK318 demonstrated significant fragmentation and a temporary stretch cavity of approximately 7 inches long by 4 inches wide, with the base reaching 16.8 inches. While both performed well at reduced velocities, the M855A1 showed a slightly shorter disruption neck.
