300-mp Powder

Every bottle of 300-mp Powder is guaranteed by a century of manufacturing expertise and the industry’s most stringent quality control processes. To maintain uniformity, the chemical composition, grain shape and size, and overall density are continually verified and evaluated in a ballistics lab.

Superior velocity and lot-to-lot homogeneity are provided with the 300-mp Powder In Stock. Power Pro 300-MP powder is a spherical powder developed for magnum pistol calibers. It has enhanced velocity and density for easy metering. Because it is tailored for certain cartridges and purposes, reloaders may make loads that are identical 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.
