Starline .223 Remington Unprimed Rifle Brass, 100 per bag

Starline .223 Remington Unprimed Rifle Brass (brand part no. 223EUP100) gives handloaders a clean slate to build ammunition around, with no primers or dents from a prior firing to work around. The .223 Remington is one of the most widely used centerfire cartridges today, tracing its roots to the .222 Remington and developed to hit specific military ballistics. In its military form it is known as 5.56x45mm NATO; the two differ mainly in loaded pressure and chamber dimensions. Brass loaded to .223 Remington pressure is safe in any firearm chambered for .223 or 5.56x45mm, but ammunition loaded to full 5.56 pressure should only be fired in a firearm labeled for 5.56mm.
