chamber mouth chamfer
If the chamfer tool was getting dull and in need of being resharpened when the chamber mouths were chamfered it could raise a ring or burr inside the chamber mouths. Removing them should cure the problem, assuming the balls are large enough. A machinist with access to a Sunnen hone could do it easily. I don't claim any expertise on this subject, but all my percussion revolvers have chambers of uniform diameter,front to rear. I have honed or reamed some of them to make the chamber diameter 0.001-0.002" over groove diameter and all the same size because I think they should shoot more accurately that way. Just my opinion.
