Description
Does M855 mean you can’t fire this ammo in your AR-15? Far from it! This 5.56 ammo by Winchester is a great all-purpose pick for any kind of range blasting fun you’ve got lined up.
This round’s 62 grain bullet is just a little more special than your average FMJ. Sure, it’s got a gilding metal jacket to drive reliable feeding and help keep lead residue out of your barrel, but its core isn’t made of solid copper. The front half of the core is made of steel.
That obviously makes the bullet magnetic, but it also makes it much better able to pierce sheet metal. At close range a bullet like this has little trouble blasting through a 1/8” thick piece of steel.
See how this ammo’s cases are discolored? That’s actually a feature: It proves the new brass cases have been heat-treated to improve their durability, so you can count on reloading them back at home. These rounds’ non-corrosive Boxer primers and clean-burning propellant support reliable performance in any semi-auto whether it’s an AR-15 or anything else!
