150rds – 5.56x45 Winchester USA 55gr. FMJ Ammo

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

Winchester’s USA ammo is your go-to standby for all of your shooting needs. If you want to train, plink, or just otherwise blast down targets, and you want to keep your wallet fatter the whole time you’re doing so, then this 5.56x45 cartridge is just the way you ought to be keeping your AR-15’s barrel hot.

This round is capped with a 55 grain projectile. It’s a quintessential full metal jacket bullet, the kind that’ll prevent lead residue from making your rifle’s accuracy sink quickly and the kind that delivers positive functionality in a semi-automatic. This bullet won’t expand in a soft target, making it less than ideal for hunting.

This cartridge further offers a new production brass casing, non-corrosive Boxer primer, and clean burning propellant. It will keep your firearm cleaner longer so you can focus on the reason you went to the range in the first place.
