1000 Rounds of 62gr FMJ M855 5.56x45 Ammo by Winchester

Want to try a new type of 5.56x45 ammunition in your AR-15? Check out Winchester’s M855 ammo – it is essentially the same stuff our troops would use to engage light personnel and vehicles, but it’s also great for casual target shooting!

This cartridge is loaded with a 62 grain FMJ, with a pure gilding metal jacket surrounding its core. Its core is made of two parts: a lead rear and a steel front. Its steel tip gives the bullet the wherewithal to penetrate sheet metal and other barriers. The M855 bullet’s two core sections may also break apart during penetration of soft tissue, which means two distinct wound channels instead of simple fragmentation.

A 62 grain bullet will do just fine when it is fired from a 1:7” barrel, but for the very best long-distance accuracy you want a 1:9” or 1:8” barrel. More importantly, this ammo’s penetrator cores will attract a magnet!

This non-corrosive and Boxer-primed ammo was produced for the commercial market and is not military surplus. But its new cases are military-grade, which means they weren’t polished up following their strengthening heat treatment.
