The 500 Linebaugh is based on the 348 Winchester cartridge cut down to 1.5 inches and inside reamed to 500 caliber. The 500 Linebaugh is the design creation of John Linebaugh, of Maryville, MO. The 500 proved to be a very successful round pushing 500 grain bullets over 1200 fps. Accuracy is outstanding, but recoil can only be described as severe. Due to its accuracy and easily handling, this cartridge could prove to be an excellent heavy game handgun cartridge and possibly the revolver cartridge suitable for taking African game.
