I spoke to a gentleman today at a sporting goods store, and he told me that this powder is THE best powder to use. He stated that he only cleans after every twenty shots with a spit patch and dry patch, and has no problems with a dirty rifle. I saw that he carried some of the pellets as well, but they were square instead of round. It was $19.50 for 100 pellets of 50 grian BP equivalent. Anyone have any experiences with this stuff?
