The FMJ is the simplest kind of bullet you’re going to find on a semi-automatic rifle cartridge. Its smooth, continuous copper-alloy jacket promotes smooth feeding from a magazine and overall cleaner performance, although it does totally preclude any degree of terminal expansion. There’s no steel in this bullet’s jacket or core, and no other ferrous metals either, for that matter. That’s just to say you have free license to go bang at ranges which forbid “magnetic” ammo.
Each bullet’s cannelure will make sure it doesn’t get knocked out of its seating while it’s subjected to recoil in the magazine. Winchester’s new brass cases and noncorrosive Boxer primers make their USA ammo a natural pick for handloading. The cases are a little discolored around their shoulders – not because they were reloaded, but because they were heat-treated at Winchester’s factory. They just weren’t polished there.
