About This Winchester 5.56x45mm AmmunitionDon’t let your AR-15 go hungry one day longer than you have to! We have Winchester’s USA label 5.56x45 ammo in stock and ready to ship at a moment’s notice – and when your order totals $100 or more, that shipping is as free as sunshine.
This is the most basic kind of 5.56 ammo you’re going to find, and that’s a good thing if your aim is to go target shooting. Each round is rigged out with a 55 grain FMJ projectile. It’s a solid lead core with a copper alloy exterior, and no steel that could attract a magnet. The bullet’s mid-body cannelure prevents it from shifting in the seating of its case, and its sleek profile means the bullet should retain roughly 59 percent of its starting velocity at 400 yards.
Winchester’s USA ammo has tough, reloadable brass cases. They have been heat-treated for added suppleness and durability, and you’re going to notice the annealing marks around the new cases’ shoulders. This ammo also has non-corrosive Boxer primers for more hygienic performance.

I've never had an issue with Winchester ammo or firearms. I have been looking for some larger size bulk ammo packages/containers at an affordable price since I have to feed the machine to spend some quality time at the range.
