Starline Cases .458 Socom 500 pieces
The .458 SOCOM is an impressive cartridge that is essentially a longer version of the .50 AE (overall length of 1.575 inches) with a set-back .308-style head and tapered to a .458-inch (11.63 mm) diameter. It has been used in some bolt-action rifles, but it owes its fame to its use in the AR-15 platform. Dies are available from most major manufacturers. This case is intended for use in properly manufactured .458 SOCOM firearms, dies, and ammunition in the USA and does not conform to the incorrect dimensions according to CIP cartridge/chamber specifications.

Warning: Some published data recommends Large Rifle primers, although this brass is designed for Large Pistol primers and most data is tailored for this. If you wish to use the higher Large Rifle primers, we recommend deeper seating of the primer pocket (0.125 inches - 0.132 inches). Seating Large Rifle primers in a standard Large Pistol pocket can lead to protruding primers, which can cause misfires and general feeding issues.
