Accurate Solo 1000 is a fast burning, single-base, flake shotgun powder. Solo 1000 was the pioneer in the clean burning revolution and is an excellent choice for trap, sporting clays, and skeet shooting. Solo 1000 is an ultra clean burning powder that is well suited for target handgun loads in 45 ACP and Cowboy Action cartridges.
