There are two predominant types of mil-spec 5.56x45 ammunition. The M193 can best be defined as vanilla with its 55 grain full metal jacket bullet. The M855, on the other hand, is another flavor altogether.

The paint on this round’s 62 grain bullet’s nose is not there for cosmetic purposes. The green means its jacket conceals seven grains of steel in its tip. The M855 bullet functions identically to a traditional FMJ as far as smooth feeding in a semi-auto and the reduction of barrel fouling are concerned, but when it strikes sheet metal at close range its steel tip helps it to pierce right through it. Its steel tip also fortifies this bullet for deep penetration of unarmored targets, and under optimal conditions reaches a depth between 15 and 20 inches in soft tissue.

This SS109 ammunition is loaded with virgin brass cases, which make it a great investment if you insist on getting as much mileage out of your reloading press as possible. Winchester’s own consistent primers and propellant deliver a fixed 3,060 fps muzzle velocity and burn up nice and clean to do so. Its slightly heavier bullet means this round will offer the best accuracy out of a 1:9 or 1:8 twist barrel.
