The military’s M80 ammo specs call for a 147 grain bullet, but Winchester’s 149 grain projectile is so close to that weight that you’ll be unable to discern any significant difference in ballistic performance. The full metal jacket bullet has a sleek profile that enhances its ability to feed smoothly as well as its ballistic coefficient. If you plan to load this ammo into a magazine, then you’ll appreciate how its cannelure keeps the bullet from jerking out of its seating during recoil. The bullet does contain steel in its jacket; it is magnetic.
This round’s bullet is not what you would want for hunting. Its inability to expand as it pierces soft tissue also makes its terminal ballistics suboptimal for self-defense, although a 7.62x51 does compensate for such a shortcoming by sheer virtue of its power.
Winchester’s M80 ammo is newly manufactured, not military surplus. Its non-corrosive Boxer primers are seated in new and reloadable brass cases. The brass is slightly discolored, but only because it wasn’t polished up nice and pretty after heat-treatment made it stronger.
