1000rds – 5.56x45 Winchester USA 55gr. FMJ M193 Ammo

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

Why do Americans love 5.56x45 ammunition so much? Because we are smart – end of story. And we’re hoping you’re an American, because that means you have the opportunity to order an entire case of Winchester USA series 5.56x45 ammunition … from us!

Don’t let this ammo’s M193 designation throw you for a loop. That doesn’t mean it’s exotic. It means it's the simplest kind of 5.56 you could select for roughing up range targets! The M193 load’s 55 grain full metal jacket projectile reliably achieves nearly Mach 3 velocity, which translates to a tight and flat trajectory. Its hard copper shell prevents accuracy-weakening deformation, and its solid lead core makes it entirely nonmagnetic.

Don’t be concerned by this ammo’s cases. They are new, strong and reloadable. They are simply cosmetically discolored around their necks because military-grade brass cases aren’t polished after they have been heat-treated at the factory. This ammo’s Boxer primers are noncorrosive and easy to replace during a handloading project.
