The .44 Magnum was far more powerful than any available handgun cartridge when it was introduced in 1956, and it achieved corresponding levels of popularity. The large-frame Smith & Wesson Model 29 still commands a nice price at gun shows, but the .44 Magnum is impressive in any firearm. As the .357 Magnum before it, the .44 Magnum once wore the moniker of "most powerful handgun cartridge in the world", the official public christening occurring in Clint Eastwood's "Dirty Harry". Of course, that was before the advent of rounds such as the mind-blowing .454 Casull and .50 Action Express. While there may be more powerful rounds available, most shooters will never care to exceed the hard recoil of the .44 Magnum. Once one adjusts to the .44's detonation (an apt description), the .44 Magnum emerges as a cartridge of maximum accuracy. Current factory listing include a 240-gr. lead bullet at 1350 fps, yielding 970 ft-lbs. of energy from a 4" barrel.
