Hornady 7mm WSM Unprimed Rifle Brass

The Hornady 7mm WSM Unprimed Rifle Brass (Hornady part no. 8639) gives handloaders a box of 50 precision unprimed rifle cases built for the 7mm WSM cartridge. Hornady manufactures this brass to consistent internal and external dimensions, which keeps chamber pressure and velocity predictable from round to round. It’s the brass handloaders reach for when building accurate, repeatable rifle loads for hunting, competition, or long-range precision work. Shipping unprimed, it leaves primer selection entirely up to you.
