Finally did it for a nose punch last night. Worked great. I was sizing the Lee .312 155gr. and the nose punch I have was smushing the ends - glue gun to the rescue. I used acetone on the nose punch and then squirted it full of glue. While it was still hot and malleable I pushed it against a plastic bag on the counter. Made it nice and flat. Clipped the overflow off with nippers and went back to sizing. Worked perfect.
