I got a Pietta 1858 remington target and its hanging up after the first 6 shots . First 6 shots all works great but then it wont cycle with out help of left hand a bit,not much. After the second cyl is fired the pistol will work like a charm again but after loading and trying to fire again it hangs up. I've cleaned the revolver and alls good for the first 6 shots again but then its hangs all over again. I shoot 3f pyrodex so its hard to believe its a fouling prob. I've tried from 17-25 g, with filler, with out filler , powder and lubed wad-ball. Nothing seemed to help. The cyl seems to get in a bind so I tried a few drops of Baristol and that seem to help but only for the first 3 shots in the second cyl. There is VERY LITTLE slop in the fitting of the cyl to the frame and I thought this a very good thing but now I wonder is it could be too tight. The gun seems to work fine if I comp clean after I shoot 6 shots but that cant be expected.
