800 Rounds of 5.56x45 Ammo by Winchester USA - 55gr FMJ

Many folks will see the words “Winchester” and “5.56x45” and know right away that they’ve found the stuff their AR-style firearms run on. Perhaps you’re one of them! But if you’re uncertain what kind of ammo you need for your Daniels Defense DDM4 V7, Ruger AR-556, SIG Sauer SIG556 or any other 5.56x45 rifle, then you can rest assured you just found it.

This ammunition is essentially the same as the M193 ammo the U.S. Armed Forces would issue for the M4 carbine. That means it has a non-expanding and nonmagnetic full metal jacket projectile, with a cannelure that keeps it securely purchased against the case mouth until ignition. The 55 grain FMJ is the most popular bullet for AR-15s owing to its economical design and great accuracy!

This is not reloaded ammunition. Its brass cases are brand new – they’re just a little gray around their mouths because they were heat-treated at the factory. Annealing makes brass more durable, so you’ll definitely be able to reload Winchester’s brass if you so please! Non-corrosive Boxer primers cut rust out of the equation altogether.
