The 45 Raptor is a rimless .460 S&W mag that was designed for use in the AR-10 platform. It can now be found in some bolt-action rifles, such as the Savage Model 10. To convert for bolt-action rifles it requires only a barrel change and for AR-10 platform rifles it requires a barrel change and a modified magazine. The 45 Raptor uses .460 S&W load data and 45 colt/454 casull or .460 S&W dies.
Barrels for both AR-10 and Savage Model 10 rifles are available from Satern Machine/Liberty Barrels. Modified magazines are available from Medesha Firearms, they can be contacted at medeshafirearms.com or by phone at (480) 986-5876.
