Like all of our N500 collection rifle powders, the N570 is manufactured from our personal high-high-quality nitro-cellulose with grains impregnated with nitroglycerine and non-energetic additives. The result: greater muzzle velocity without having greater chamber tension and without the need of increased don within the gun!
