So just cause I'm thinking about it right now..... I've got a .32 cal pedersoli Kentucky I built and the vent liner protrudes into the breech. So I have to remove it to clean the gun. Is this normal? Would I be in the wrong to find a way to blue the protruding part and then file or cut it down? Lathe is out of commission at the moment. I don't think I could chuck it in the 3 jaw and we don't have a collet head at home. I don't really like taking it out every time I shoot it.
