Reloder® 15 is a medium rifle powder with a broad caliber range, and is consistent at all temperature conditions. Great for high-velocity varmint rounds, while the best, all-around, medium-speed rifle powder available. So good, that the U.S. military has selected this powder for use in its M118 special ball, long range sniper rounds.
