Every container of Alliant Smokeless Powder is backed by a century of manufacturing experience and the industry’s most stringent quality control procedures. To ensure consistency, the chemical composition, grain shape and size, and overall density are constantly checked and tested in a ballistics lab.
Superior velocity and lot-to-lot uniformity are provided by the Power Pro 300-MP. Power Pro Alliant 300 MP powder is a spherical powder designed for magnum pistol calibers. It has improved velocity and density for easier metering. Because it is designed for specific cartridges and applications, reloaders will be able to create a load that is similar to factory loaded ammunition. 22 Hornet loads are used as secondary 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.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
