Videos tagged with M855A1 EPR

This video analyzes the terminal performance of the Mk318 Mod1 ammunition. Fired from a 10.5" upper receiver into calibrated 10% ballistic gelatin, the test assesses penetration, retained weight, and recovered dimensions. The description references the ammunition's development during the Global War on Terror (GWOT) as a contender against M855A1 EPR, highlighting Mk318 Mod0 and Mod1 as close alternatives. The video provides detailed ballistic gel test data, including impact velocities, penetration depth of 25 inches, and recovered projectile measurements. It is presented as the "new hotness" for the Marine Corps.

This test evaluates the M855A1 EPR round's terminal ballistics at reduced velocity (1,988 FPS) using a 10.5-inch barrel. Despite the lower speed, the round demonstrated significant fragmentation and a substantial temporary cavity in ballistic gel, penetrating 16.3 inches. This velocity is equivalent to a standard 14.5-inch barrel shot at 350 meters, highlighting the round's effectiveness against tissue and barriers.
