IMR Trail Boss

Trail Boss was designed specifically for low velocity lead bullets suitable for Cowboy Action shooting. It is primarily a pistol powder but has some application in rifles. It is based on a whole new technology that allows very high loading density, good flow through powder measures, stability in severe temperature variation, and, most importantly, additional safety to the handloader.

Hodgdon Pistol Data
case: Starline; bbl: 10.743"; PR: Winchester LRM; twist: 1:20"; trim: 1.790" - This data was developed with Starline Brass which was designed for use with large rifle type primers. Some brands of brass were designed solely for use with large pistol primers. Check with the manufacturer of the brass for correct primer usage. Rifle primers used in a pistol primer pocket cannot be seated sufficiently deep to be below flush with the casehead, which could result in sympathetic ignition of other rounds in the cylinder during recoil. Such use may result in damage to the firearm and/or result in injury or death of the shooter and/or bystander. Never exceed loads listed.
