IMR Trail Boss Smokeless Powder 9 Oz
by HODGDON , IMR & WINCHESTER
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. Grain shape is round, flat and hollow.
