Do you cringe whenever someone calls a magazine a clip? We sure do! That’s why we love this ammunition by Winchester – it gives us an opportunity to use the word “clip” in the right context (not counting what we do to our toenails). This box contains three clips, each of which holds 10 rounds of AR-friendly American-made 5.56x45.

This round’s bullet is a little heftier than usual at 62 grains, thus enabling it to conserve more momentum and strike with greater force. On its outside the bullet is just a normal full metal jacket, with a gilding metal shell and solid point nose profile. The green paint indicates what’s special about the M855 bullet: the solid steel insert which makes up the frontal section of its otherwise solid lead core. Its steel tip enables the M855 projectile to penetrate barriers more effectively – but it also quite naturally means that the bullet will attract a magnet. That’s why this ammo’s not acceptable for use at all commercial ranges, so take care!

This noncorrosive Boxer-primed ammo is loaded with brand new brass cases. They are indeed discolored, but that isn’t because they were previously fired and reloaded. Every brass case is heat-treated at the factory. The annealing process makes brass stronger. Commercial ammo cases are typically polished after they’re annealed. Military-grade cases aren’t polished, because cosmetics don’t count for anything on a battlefield and militaries like to see proof that their ammo was manufactured correctly.
