500rds – 5.56x45 Winchester USA 55gr. FMJ Ammo

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

Winchester USA. The most American name a 5.56x45 cartridge can have. Whether you’re looking forward to absolutely annihilating all the recyclables that have been gathering dust in your shed – or doing some truly serious training – this 500-round box of military-grade ammo will win your full satisfaction.

Nothing wrong with shooting targets with the simplest type of bullet on the market. Each round’s bullet weighs 55 grains (or extremely close to it), features a nonmagnetic lead core and copper-alloy jacket, and races out of a 20” barrel at a velocity of 3,180 fps. Low fouling. Flat trajectory. Zero capacity for terminal expansion. Perfect for when you’re taking aim at inanimate objects.

This ammo’s cases are fresh out of the factory! Their necks and shoulders are a little discolored, no doubt about it, but that’s only because Winchester didn’t bother giving them a polish following the heat-treatment phase of their creation. Is this ammo loaded with noncorrosive Boxer primers? You bet – and it’s reloadable.
