The Power Pro™ Series of canister spherical powders has been designed and engineered to provide exceptional round performance in light, medium, or magnum rifles. Improved velocity and density enables more efficient reloading and when duplicating certain factory ammunition loads. Powders are use-specific: 300MP for magnum pistols; Varmint is selfdescriptive; 2000MR and 4000MR for magnum rifles, and 3000LR for light rifle applications.
