Freedom 223 62 gr SS109 Reman ($5.99 Shipping! Orders $200 - $2000)

The U.S. designated the SS109 cartridge the M855 and first used it in the M16A2 rifle. The 62-grain round was heavier than the previous 55-grain M193. While the M855 had better armor penetrating ability, it is less likely to fragment after hitting a soft target. This lessens kinetic energy transfer to the target and reduces wounding capability.
