Jagemann Unprimed Brass Rifle Cartridge Cases .223 Rem 100/bag

The .223 Remington (.223 Rem) is a cartridge with nearly the same external dimensions as the 5.56 x 45 mm NATO military cartridge. The dimensional specifications of 5.56 NATO and .223 Remington commercial brass cases are identical. The cases tend to have similar case capacity when measured with variations chiefly due to brand not 5.56 vs. .223 designation. The result of this is that there is no such thing as •5.56 brass• or •.223 brass• the differences in the cartridges lie in pressure ratings and in chamber leade length not in the shape or thickness of the brass.

Drawn from premium American-made brass cups Jagemann casings are rigorously tested to ensure unparalleled durability and dependability each casing undergoes rigorous in-line and postproduction quality assurance testing to ensure a flawless casing.

Standard casing dimensions and tolerances have been modified to achieve maximum performance. Jagemann Sporting Group•s in-house tooling and engineering capabilities provide the ability to customize casing dimensions for use with specific projectiles.
