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.
The Alliant Power Pro 4000MR has excellent velocity and lot-to-lot uniformity. The 4000-MR powder is a spherical powder designed for magnum rifle calibers, with 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. The Power Pro 4000MR powder performs admirably in 7mm and 300 Winchester Magnum cartridges.
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.
