History-
When introduced in 1873 for the Colt Single Action Army, the .45 Colt was a powerhouse of a pistol cartridge. Initially, the cartridge had a 255-grain bullet propelled by a case full of 40 grains of black powder. The cartridge was undoubtedly a man-stopper and horse killer, and many troopers had difficulty controlling the recoil. After a few years, the powder charge was reduced to a more manageable 28 grains of black powder. 
The Cowboy .45 Special was first designed by “Adirondack Jack,” a dreamer who took the cartridge from conception to producing 500,000 for the hungry market. Since then, boutique ammunition companies for the Cowboy Action market have produced the C45S. Clearly, it’s not meant for big game hunting but for plinking or steel competition, it fills the bill very nicely.

$48 per 50ct box or $450 per 500rd case
