Winchester makes this 5.56x45 ammo right here in America with their standard Boxer primers and clean-burning powder. Now, a lot of our customers ask if brass cases like these have already been fired. Not at all – the case’s discoloration just shows it was heat-treated at the factory. Military grade ammo often isn’t buffed up before it’s shipped out.
This round’s 3,180 fps muzzle velocity is just a tiny bit slower than the usual M193 round’s 3,250 fps, but at that rate the bullet still hangs onto the flat trajectory you’ll need for good accuracy. The bullet itself is an FMJ. It doesn’t do anything fancy after it hits its target, which isn’t to say an FMJ can’t do a lot of damage even without expanding. But at the end of the day most people would recommend this ammo’s nonmagnetic bullets strictly for target practice.
