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.

A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge.
