I have used "Trail Boss" most sucessfully in my ML colt SAA copy. (we cant have cartridge pistols as you know) I used a cylinder full underneath a 125 GN SWC and the accuracy was scary. I am not the best pistol shot but we have an ex olympics pistol shot at the club. He put six offhand @ 25 yards into a 2" group.. It burnt great was mild in recoil and I would like to experiment a lot more with it but have not the time. I think that it could be a great powder for all sorts of NFB applications.
