Once again I am down to my last pound of goex 2f. The last time I found it was in Bismarck at a small gun shop. I bought the last 4 lbs that were going to be sold in the store. Now comes the long journey of trying to find another source. I am heading down to Sioux falls in a couple of weeks so maybe I can find some down there. In the mean time I am thinking about trying pyrodex P in my gpr .54 with a prb. Has anybody had good luck with this combo?
