Lapua Unprimed Cases Features The Lapua Unprimed Cases in .223 Rem are engineered with a hard strong base that holds primers tight in the primer pocket even after repeated reloading preserving consistent ignition over many firing cycles. The brass body section is similarly hard and firm allowing for easy extraction whether full length sizing or neck sizing is used during reloading. Strict tolerances in concentricity and wall thickness are maintained in the neck which is annealed to withstand the stress of repeated firing and resizing. This combination of careful engineering at the base body and neck gives reloaders a case built to perform consistently over a long service life. Each box contains 100 pieces of unprimed .223 Rem brass sized for small rifle primers and suited to both hunting and target shooting applications. Lapua s advanced metallurgical research and manufacturing processes are aimed at delivering leaders in uniformity and quality among rifle brass supporting the kind of precision handloaders expect from a top tier case. Because the .223 Rem is among the most widely used rifle calibers this brass gives reloaders a dependable option for building match grade or hunting loads from the ground up. These cases arrive unprimed and are intended solely as reloading components not as finished ammunition.
