This particular configuration features the more uncommon Winchester WMA headstamped M855A1 packed in the original 30 round cardboard sleeves and packed in the original cloth bandolier complete with loading tool. Very limited quantities.
The M855A1 is a significant leap forward from the M855. One of the most notable improvements is using a non-lead core, which enhances penetration capabilities. The M855A1 features a steel penetrator tip and a copper alloy jacket designed to improve accuracy and lethality. This design ensures better performance against hard targets and reduces the chances of over-penetration in soft targets.
Ballistically, the M855A1 is superior to standard 5.56 rounds in several respects. It has a higher muzzle velocity (3113 fps, 1334 ft. lbs.) and maintains stability and accuracy over longer distances. The round’s aerodynamic design reduces drag, allowing for a flatter trajectory and more consistent impact. This difference means greater effectiveness, especially in long-range engagements.
The M855A1 Ammo also performs better against steel armor than the standard M855 and its predecessor, the M193. While the M855A1 is not an armor-piercing round, it does offer improved penetration and can defeat many body armors in a repeat-hit scenario.
The Army also reports that the M855A1 displays better terminal performance. That speaks to the overall versatility and effectiveness of the round in combat scenarios.
