Im reloading British .303 and trimming the cases on a Lyman Hand Trimmer. I had to buy a #31 Pilot for the case mouth and found that it will not go into the mouth all the way. Only goes in half way after I have sized the cases. A #30 Pilot will fit easily but on occasion will stick in the mouth when I retract the cutter. Am I doing something wrong ? Appreciate the help.
