Lyman’s GPR hammer needs adjusting

[timetraveler]

Hello all, first post. I have an older GPR and the hammer doesn’t come down on the cap cleanly. It needs to be moved forward or bent open a little. Right now the front rim of the hammer hits the cap first but the hammer force pushes it the rest of the way down. The gun fires fine but I’d like to fix it but don’t know if it’s possible. Can a gunsmith heat the hammer and bend it open a touch? I don’t see any other way. I saw an offset nipple but the threads were different. Anyone have a suggestion? Should I dremel the front rim off so it doesn’t skip off it? Don’t really like that solution either. I got to say the gun is a shooter, I’d like to fix it.
Thanks, glad I signed up. I actually did years ago but never posted and when I tried to sign in it wouldn’t let me.

Something as simple as a shorter nipple might solve your problem. I personally would not dremel open the hammer cup.
