Alliant Power Pro 300-MP Smokeless Powder In Stock

Every bottle of Alliant Smokeless Powder is guaranteed by a century of manufacturing experience 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 Alliant Power Pro 300-MP. Power Pro 300-MP powder is a spherical powder designed for magnum pistol calibers.

Alliant Power Pro 300-MP has improved velocity and density for easy metering. Because it is tailored for certain cartridges and purposes, reloaders can make loads that are 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.

Why is there no Alliant Powder?

Alliant Power Pro 300-MP

Why are your powders so difficult to find? The industry’s ability to keep items on the shelf at most retail shops has been overwhelmed by record demand for commercial ammo, powder, and other reloading components.

What is Power Pistol Powder?

Power Pistol smokeless powder is dual-based, fast-burning, consistent, economical, and exceptionally accurate, making it a great choice for high-performance semi-automatic handguns such as the 9mm Luger, 40 S&W, and 10mm Auto.

Which Gun Powder is Best?

Many shooters choose Hodgdon H4895, Varget smokeless powder, and Accurate 4350 powder. They are excellent selections for a wide range of bullets and cartridges. IMR 4350 smokeless powder is another popular contender for finest all-around smokeless rifle powder.
