Vihtavuori N300 reloading powders for handgun and pistol
The N300 series powders are ideal for handgun and shotgun loads.
A New and Advanced Process Added to our N300 Series powders!
We have recently undertaken some major improvements in the production of our high-quality N300 series powders. This newest change involves the application of graphite as a finishing step in production. As always, our smokeless powders undergo a stringent series of quality control checks throughout the manufacturing process. Before it ever ends up in a reloading bottle, we’ve checked and rechecked it at every step of the way. Our goal is to continuously improve our powders to give our reloading customers every possible competitive advantage in any shooting discipline.
In this latest improvement, we have changed the manner in which the nearly completed powder is given its final coating. Graphite is added to the surface of these powders during the vacuum drying stage. The graphite serves to eliminate static electricity, and makes the finished powder flow smoothly and evenly through loading machines and powder measures.
