At the range the other day, I finally started to have some ignition problems with my previously dead reliable Lyman GPR. Usually I fill the pan about 1/2 full with FFFF, and tilt the rifle to the right to get it away from the touchhole,avoiding the "fuse" effect. For some reason, after the first shot which fired with almost no delay at all, I was getting nothing but flashes in the pan over and over. I picked the flashhole, then tried again. Still no luck! Checked the flint-excellent spark! ***? Pulled the touchhole liner, cleaned it out well with a pipe cleaner, then reinstalled. Another two shots were sort of slow, and then more flashes in the pan! Pulled the ball, dumped the charge, and did a full cleaning with bore brush and patches. Another shot or two were fine and then more flashes in the pan! I noticed while pulling the touchhole with a loaded charge, that the powder wasn't running fully back to the breech. Also noticed that I can't run a screw or any other fullbore cleaning device back to the breech, as if there is a coned breech of some sort that has become fouled. I temporarily solved the problem by doing what I usually get horrible results from doing-filling the pan up against the touchhole. Normally that gives the "fuselike" hangfire, but in this case it worked.
So, does anyone know if their should be any change in the barrel diameter forward of the touchhole on a GPR?
