Reloading The .50 Action Express

This is the Desert Storm Cartridge. It came to market as a commercial cartridge in 1991. The case while large enough for the .50 cal bullet, has a rim that is the same size as the .44 Magnum. So a case holder for the .44 works fine for reloading this round. However, some who have tried it, report that the shell holder for the .45 Colt or .454 Casull work better. You can try both and see which you prefer. In 1993 several other pistols came out for this caliber, and recently a Freedom Arms Single Action Revolver for the .50 AE.

Loads for .50 Action Express:
(Note: These are near maximum loads, you should use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Bullets are .500" in diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.
