20rds – 223 Rem Winchester USA 55gr. FMJ Ammo

Winchester Ammunition 55 Grain Full Metal Jacket (FMJ) Ammo Details

Winchester makes what is without a doubt some of the most popular 223 Rem range ammunition in the country. It doesn’t matter how talented you are – or how novice. This is the ammo any AR-15 needs for target shooting!

This cartridge is loaded with an ordinary 55 grain FMJ projectile. It’ll achieve 3,240 fps velocity right out of the barrel, and its ensuing 0.274 G1 ballistic coefficient means it should stay supersonic until almost 800 yards. It’s going to serve up that flat trajectory which makes precision shooting more manageable – which isn’t to suggest this ammo’s not good for rapid-fire mag dumps, too!

Winchester’s FMJ is nonmagnetic – no steel lurks in its core or its jacket.

These USA label cartridges are loaded with non-corrosive Boxer primers and fresh brass cases. The brass is gray in the places where it has been heat treated. That means it’s more supple and dependable, not that it has been previously reloaded!
