Reporting back.
Last Sunday, I took the rifle down the road to the local black powder club's monthly shoot.
Of course, I got there late and missed one relay, but I really wasn't there for the competition, I just wanted to see how the rifle worked with the percussion setup.
Observations:
With RWS rifle caps and MSM Spitfire nipples, the ignition was crisp with no hangfires, misfires or other pesky problems.
Obviously, I had no problems with worn out flints, either.
Although the Leman hammer didn't line up with the nipple perfectly, it didn't seem to make any difference.
A torn rotator cuff does not make for a steady hold. I think at 100 yards, I could shoot at the center of a 2' culvert and some of the shots would still land outside of it.
I am liking this and I think if I do some shooting off a bench, I should be able to get the load worked in and then adjust the sights for the new ignition.
