.44 Magnum cartridge

Based on the .44 Magnum cartridge, a revolver designed for the .445 SuperMag can fire the shorter .44 Magnum, .44 Special, and .44 Russian rounds.

A super magnum is a longer and/or more powerful version of a “magnum” cartridges. Although the term “super magnum” typically refers to a handgun cartridge, created by lengthening an existing straight-case design, it can also refer to a rifle cartridge, such as the .17 Winchester Super Magnum (WSM).

The most widespread of these cartridges are the “SuperMag” family of super-magnum handgun cartridges that were proposed and tested by Elgin Gates in the 1970s.
