A century of manufacturing know-how and industry-leading quality assurance measures go into every jar of Alliant Smokeless Powder. Constant monitoring and testing in a ballistics lab ensures that the chemical composition, grain size, and total density remain constant.
With the 4000-MR Power Pro, you can expect lightning-fast processing times and consistent results from batch to batch. The 4000-MR powder is a spherical powder with increased measuring speed and density specifically made for magnum rifle calibration. Reloaders can create a load that is comparable to factory ammunition because it is tailored to specific cartridges and uses. The 4000 MR powder gives 7mm and 300 Winchester Magnum cartridges exceptional performance.
This powder will be delivered to you by the heat. If you’re coming up on a heavy lift in chasing cartridges, you’ll need magnum loads suitable for dangerous or big game. This is a highly effective, reliable, and uniform powder.
