As a rifle or carbine cartridge the .44 Magnum is sufficiently powerful for medium-sized game, yet fits easily into a compact, lightweight package. In 1961, Ruger introduced their .44 carbine, the first .44 Magnum carbine. The lever-action Marlin Model 1894, and many other firearms are currently available in this caliber. With significantly longer barrels than revolvers and no cylinder gap (except in revolving rifles), carbines will generate a significantly higher velocity than a revolver loaded with the same ammunition. Tests with various ammunition in the Ruger Deerfield yielded a velocity of over with a bullet, comparable to the muzzle velocity out of a revolver. Loads using slow burning powders maximize performance in both short and long barrels, with one published load generating from a revolver, and from a carbine with a bullet.
