This came up on another forum, before I start filing I wanted a few opinions from the experts.
I have a GM 13/16 40cal barrel and a Chambers Late Ketland lock I am going to put in my current TN/NC gun build. The barrel has a long threaded breech that will put my touch hole and lock " down the barrel" mighty far if I use it as is.
I have 4 flintlocks from different builders(two I built) and time frames, the back edge of the snails on three out of four of them line up with back of the barrels.
Is this the most desirable position to achieve for the proper lock/ barrel configuration or do you fudge a little for more useable breech threads?
