.50 McMillan Bros. (Fat Mac) - http://ammoguide.com/?catid=445

Also called the 12.7x67mm, this cartridge is based on the 20mm artilley/cannon round. Developed by the late Gale McMillan and his son Rock, the round was introduced by McMillan Bros in 1996.

The "Fat Mac" was targeted for long-range Fifty Caliber Shooters' Ass'n. (FCSA) competitions.
