This past weekend, I shot my 1860 Army Uberti for the first time and a slight issue. I was told to get #10 percussion caps. With gun totally loaded, I pull hammer back and pulled trigger,....click... Gun not shoot. I would do this usually about two entire cylinder complete revolutions. Meaning, I would shoot 12 times with gun not firing. After all that, the third time for each load, then it would fire. Problem is with the procussion caps. Is the #10 caps, just a little bit to small for my specific gun??
