Each bottle of Alliant Smokeless Powder is backed by a century of manufacturing experience and the industry’s most strict quality control systems. To maintain uniformity, a ballistic laboratory continually monitors and tests the chemical composition, grain shape, size, and overall density..
The 4000-MR Power Pro provides improved speed and consistency from lot to lot. The 4000-MR powder is a spherical powder intended for magnum rifle calibration and provides superior measurement speed and density. Because it is tailored for certain cartridges and usage, reloaders can produce a load that is similar to a load of factory ammunition. The 4000 MR powder provides superior performance in 7mm and 300 Winchester Magnum cartridges.
