Not to drag this out,as I’m itchin to get on to that Fowler project,but is it usual to have short flint life on a new lock? I was using “French Amber†flints on my first range outing and after 3-4 shots my flints were sparking but not enough to fire,even after wiping them and the frizzen .whe I changed flints again great spark and great ignition,it is as mentioned a L&R lock and seems to hit really strong, I have to try black English flints next
.I also discover the lock is not tight enough to the barrel ,after reworking the inlet depth awhile it’s still not tight ,I also discovered with a straight edge the barrel side has a concavity with the flash hole being center of it , not much ,but enough to always have a slight gap there between the barrel and bolster ,can’t explain how unless a rookie at Lyman made it while fitting it? I may have to file it flat myself as I get fouling in the lock areas and maybe other unwanted stuff .if I put a straight edge on it and shine a light from behind I can see it.
