“M193” is the military’s designation for the the most basic kind of 5.56. Federal puts an X in front of the designation to indicate that this particular ammo was manufactured for the civilians instead of the uniforms. Each round is loaded with a 55 grain full metal jacket projectile. The jacket’s cannelure keeps the bullet securely seated in the case mouth while recoil jerks it backward in the magazine. The jacket is made of copper alloy and surrounds a solid lead core, thus making the entire bullet unable to attract a magnet.
This noncorrosive Boxer-primed range ammo features all-new and reloadable brass cases. The cases are indeed discolored, but not because they were previously fired. Military-grade cases just aren’t shined up for better cosmetics after they were heat-treated for added durability and reliability!
