Every container of Alliant Smokeless Powder is backed by a century of manufacturing experience and the most exacting quality control procedures in the industry. Chemical composition, grain shape and size, and overall density are constantly checked and tested in a ballistics lab to ensure consistency.
Power Pro 300-MP offers superior velocity and Lot-to-Lot uniformity. A spherical powder designed for magnum pistol calibers, Power Pro 300-MP powder delivers improved velocity and density for easier metering. Because it’s designed for specific cartridge and applications, it will allow reloaders to create a load similar to factory loaded ammunition. Secondary use includes 22 Hornet loads.
Warnings from the Manufacturer:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
