The .38-55 Winchester

By Chuck Hawks


Ballard introduced this old timer in 1884 for their single shot target rifles. Its nomenclature is derived from its approximately .38 caliber bullet (actually .375"), and the 55 grains of black powder with which it was charged.

Winchester, alone of the Big Three ammo companies, offers a .38-55 factory load. This uses a 255 grain soft point bullet at a muzzle velocity of 1320 fps with 987 ft. lbs. of muzzle energy from a 24" barrel. At 100 yards the velocity of this load is 1190 fps with 802 ft. lbs. of energy, and at 200 yards it is moving at 1091 fps and carrying 674 ft. lbs. of energy.

The handloader can achieve better ballistics than those provided by the Winchester factory load. Sierra offers a .375" 200 grain JFP Pro-Hunter bullet, and Hornady offers a 220 grain JFP bullet (SD=.223). These can be driven to about 1600 fps, stretching the effective hunting range of the cartridge to about 150 yards.

According to the Lyman 47th Reloading Handbook the Remington 255 grain JFP bullet can be driven from a 26" barrel at a MV of 1271 fps by 31.0 grains of IMR 3031 powder, and a MV of 1805 fps by 35.0 grains of IMR 3031. Remington cases and primes were used for these loads. This Lyman data is intended to be used in modern rifles, such as recently produced Winchester Model 94's, only. The sections of older Lyman Reloading Handbooks devoted to obsolete cartridges are also good sources for reloading information on old cartridges like the .38-55.

For target shooting, most competitors use cast bullets weighing around 250 grains at 1200-1300 fps. These are usually propelled by fast burning powders like H4227, IMR 4227, or SR4759.
