800rds – 223 Rem Winchester USA 55gr. FMJ Ammo
Winchester Ammunition 55 Grain Full Metal Jacket (FMJ) Ammo Details
The average AR-15 has a maximum effective rate of fire in the ballpark of 40 to 50 rounds per minute. That means you’ll get at least 20 minutes of enjoyment out of this 800-round case of 223 Rem ammo by Winchester. If you approach it a little more realistically, however, then this case is a great investment in hours of range time fun!Winchester’s USA label ammo is suitable for all training, target shooting and plinking applications, although this ammo is not at all unlike the 5.56x45 M193 rounds our Armed Forces would use during combat. The straightforward 55 grain FMJ has pure lead core and copper alloy jacket. The nonmagnetic bullet thus feeds efficiently, mitigates barrel leading, maintains a flat trajectory, and poses a significant chance of splintering apart into shrapnel if it hits soft tissue within around 180 yards.
See how these rounds’ cases are gray around their necks? That’s actually a feature. It demonstrates that the brass was annealed at the factory, a process which makes it more supple to promote reliable functionality and repeated reloadability. This American-made ammo is non-corrosive and suitable for all 223 and 5.56 firearms.
