5.56X45 WINCHESTER USA 55 GRAIN FMJ (150 ROUNDS)

About This Winchester 5.56x45mm Ammunition

Winchester’s USA ammo comes in a white box that’s synonymous with reliable performance coupled with great value. If you’d like to destroy a few targets while keeping you wallet mostly intact, this 5.56x45 cartridge represents a great investment.

This round features the 55 grain projectile that casual and serious AR-15 marksmen alike enjoy. The bullet’s full metal jacket has been consistently drawn around its lead core, making it accurate enough to find its way steadily downrange. That it bears a jacket means this round’s projectile will not expand, but its tendency to prevent rapid bore fouling and feed effortlessly through a semi-automatic makes it ideal for cost-effective target practice.

This cartridge’s factory fresh brass casing has the uniform dimensions required for efficient feeding and ejection as well as dependable performance. Winchester’s own non-corrosive primer ensures this round will not only ignite properly, but also that your rifle’s action and bore won’t accumulate caustic salts.
