I have worked on a couple of Pietta 1858s. The cylinder chambers were smaller than the bore. Accuracy was poor. Once I opened them up to 0.452" and use oversized balls accuracy was great. This seems to be a common flaw with percussion revolvers. A lot of guys use filler and a small charge. I speculate that the filler acts like a wad and minimized gas blow by.
