About this powder
Accurate MagPro is a slow-burning ball powder for ultra-magnum rifle cartridges. Its ball shape provides consistent metering even at the heavy charges required by .338 Lapua and .300 Ultra Mag. Particularly valued by hunters who want the metering convenience of a ball powder in ultra-magnum applications where extruded powders can be difficult to dispense accurately in the field.
