Starline Cases 5.56x45 Nato 100 pieces
The 5.56x45mm NATO is the military version of the .223 Remington, one of the most widely used centerfire cartridges today. The 5.56x45mm brass from Starline is identical to the .223 Remington brass from Starline, except for a slight change in metallurgy, which makes it harder at the base of the case. When Starline's .223 brass is loaded with .223 Remington pressures, it can be used in all firearms designed for .223 or 5.56x45mm. When loaded with 5.56 pressures, you must use firearms that are marked for use with 5.56mm. It can be unsafe to fire 5.56mm ammunition in firearms with a .223 Remington chamber.
