Starline Brass Star45specia Unprimed Cases 45 Special 50/Pack

The Cowboy .45 Special is a case that is optimized for use with light loads in .45 Colt caliber revolvers for Cowboy Action Shooting. Light loads with excessive airspace are a recipe for case splits and erratic function. By using the Cowboy .45 Special case, with its .45 Colt rim and .45 Auto length, the problem no longer exists. While many claim .45 Auto load data can be used in this caliber, it is important to realize the limitations of the firearm's chambering, and to only use loads that fall within the pressure range of that firearm.
