Picked this one up this morning for a Ruger new model single six (one of my clunkers) and a c-note, so I guess I have 300 buck in it. It is a 58 caliber made by Pedersoi that is pretty clean and not shot too much judging from the frizen. I have some .015 patches for my .570 round balls to feed it, does this sound right? I was thinking of starting with 40 grains of 3f and working form there. See yeall at the range.
