This video from AyoItsMike delves into the common debate surrounding 5.56 Green Tip (M855) versus standard 5.56 FMJ (M193) ammunition. While the green tip is often perceived as superior due to its steel core penetrator, the speaker suggests it may offer minimal practical advantage for typical range use, questioning if the difference is merely cosmetic. The content highlights a common discussion point within the firearms community regarding ammunition performance and perceived value.
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.
