I have some of this powder laying around, probably 15+ years old, and was wondering if anybody out there has used it in 44mag cases, or other similar handgun type rounds. I'm just looking for a way to use up this powder and get some cheap plinking loads for my marlin 1894ss. It might be interesting to see what primers set if off best as well. I tried some regular pyrodex in my 357 mag revolver, and all I got was a locked up cylinder after about 12-18 rounds. Any suggestions?
