The cartridge is essentially a 44 Magnum case with approximately 3/8 inch added to the overall length. As is the case with the 44 Magnum, the name is somewhat misleading as it uses bullets of .429 inch diameter. The 445 Super Magnum however, can drive the same bullets nearly 300 fps faster than the 44 Magnum. For those willing to put up with the muzzle blast and recoil, this caliber could prove to be an excellent choice for competition silhouette shooting or handgun hunting of large game. With more and more bullet manufacturers producing heavy jacketed bullets in this caliber of 300 grains and up, this cartridge can really come into its own.
