m&p45acp10+1. I have the same problem finding real black powder so I went to Pyrodex P for the .36 cals and Pyrodex RS for the .44 cals. One thing cought my eye on your last post and that is with triple 7 it dose not like to be packed tight like real bp or Pyrodex. So when you put your powder in with a lubed wad and filler remember not to compress triple 7 real tight. Just enough to know you don't have an air space. Have fun with it. Let us know how it works out.
