Brownells 75th Anniversary - A Shooting Heritage

Magnum rifle powder with exactly the same burn rate as standard IMR 7828 and uses the same data. Its super-short granulated powder meters nearly the same as spherical powders and allows more powder in the case,so it yields more velocity than standard 7828 in many loads.
