Looking to play with other powders and ran across this in my journey. Slow powder for various cartridges. Has anyone had experience with it? Any other calibers that's not listed on alliants site that it's useful for. I already have plenty of turtle powders of different kind. But it's 120/8# so thought I'd toy with it
