A local store has Blackhorn @ $19/can. I’ve always wanted to try this powder for some of my old-style revolver cartridges. Would this powder be appropriate for .32 S&W, Long, and H&R, or .38 Short/Long Colt or Specials (all fired from modern smokeless powder firearms)?

Just wondering. That seems like a pretty good price, even if it is only 10 oz.
