Winchester - Full Metal Jacket M193 - 55 Grain 5.56x45 Ammo - 20 Rounds

Winchester’s USA label 5.56x45 ammunition is a great buy whether you’re a rookie or a seasoned shooter. White box ammo offers real reliable performance, made only better by being made in America!

This cartridge sports a full metal jacket, which at 55 grains provides a 3,180 fps muzzle velocity. That’s more than adequate pressure to cycle an AR-15, and fast enough to deliver the flat trajectory which facilitates long-distance shooting. Count on Winchester’s consistent FMJs to feed efficiently from a magazine, preempt rapid barrel fouling, and deal well over 1,000 ft lbs of energy at close range. This round’s bullet has no steel and is not magnetic.

Winchester’s non-corrosive primers and clean-burning propellant add up to better functionality, as your rifle won’t quickly foul up with excessive residues. This ammo’s military-grade brass cases are freshly drawn and tapered to precise dimensions. They have even been heat-treated for greater durability, which you can see for yourself from their gray necks and shoulders.
