This is the cartridge that gave birth to the 30-30. The 30-30 is simply the 38-55 necked down to accept a .30 caliber bullet of .308 diameter.

The 38-55 is not an obsolete cartridge. Several manufacturers still offer the 38-55 in their rifles, both single shot and lever action. The 38-55 is also still considered the preferred thin skin game taking cartridge there is. Millions of rifles have been chambered in this cartridge and loaded properly is effective on brown and black bear.

The 38-55 was first developed by Winchester in 1876 by Ballard. The 38-55 was first used by Marlin in their lever action rifles and then by Winchester in their High Wall and lever action rifles.

The .38-55 is renowned for its exceptional accuracy at ranges up to 330 yd and properly loaded and developed by the loader can be accurate out to 1000 yards. The maximum CUP pressure for the 38-55 is 30,000 but will create a explosive combination in older turn of the century firearms made in the early 1900's and late 1800's as this was originally a black powder cartridge, 38 caliber under 55 grains of powder. It was originally intended as a true .380 dia. cartridge, however rifle manufacturers from the cartridge's inception still cannot get it right and grove diameters range from .375 to .382. Therefore you should always swag your barrel to determine what your grove diameter is before you choose a cartridge. To solve this problem, in lead bullets we use a .379 bullet and limit our speed to a maximum of 1300 fps to prevent leading. With a gas check you can go safely to 1600 fps but gas checks are not allowed for Cowboy Action shooting in their side matches. Jacketed bullets can safely be loaded up to 1800 fps. There are no lead free/copper bullets for this cartridge. The Winchester 375 is a modern variant of this cartridge. NEVER EVER use .375 Winchester ammunition in ANY 38-55 EVER for any reason. If you do you may be making a trip to the hospital and most probably will by replacing your rifle.
