The .44 Auto Magnum Pistol (AMP) is a large-caliber, semi-automatic pistol cartridge developed in 1971 by Harry Sanford.[2] The primary use is in the Auto Mag Pistol.[3] The cartridge was also employed in the Wildey automatic pistol, including a few other custom pistols.[4] While factory loads are manufactured, cases can be made by cutting down and reaming out .308 Winchester or .30-06 Springfield brass,[5] with ballistic performance similar to the .44 Magnum revolver cartridge.[3]
The .44 AMP was discontinued in 1982 after eleven years before being brought back sometime later in 2017, continuing current production to the present time. Starline makes brass with the proper dimensions and headstamp for handloading use.[6]
