I did dress the frizzen to pan contacts a little bit, as there were some high points creating daylight, then with the lock off of the gun, I filled the pan with 4F and held my thumb over the hole, where the flash hole would be on the barrel, and shook the lock, every which way but loose, to see if I could loose any powder, and never really seemed to loose any powder.
However, lockplate to barrel fit up is not tight, and I believe that is the main problem. And I have since closed it up a little bit, by doing a little of cleaning up on the lock mortise. It's not perfect, but it is a lot better.
In the process, I believe I have learned a lot, about correct fit, on these here rocklocks, which sure ought to help me in the future to trouble shoot, and also evaluate a flintlock's correctness, or lack there of.
