This is an M193 cartridge, which makes it the most basic kind of 5.56 cartridge. Its bullet weighs 55 grains so it can rip out of the muzzle at 3,180 fps, and it keeps traveling faster than Mach 2 beyond 250 yards. The bullet itself is a full metal jacket – just a lead core and copper alloy exterior, with no fancy bells and whistles that enhance terminal ballistics. That’s why M193 ammo is recommended for target shooting and not home defense.
This ammo’s brass cases are not reloaded. They are discolored because they were heat-treated at the factory, making them stronger and good for handloaders. Winchester’s uniform bullet weights, propellant charges and noncorrosive primers make this nonmagnetic ammo a great pick for any kind of recreational shooting!
