I had thought about the epoxy thing too, but I don't load too many of these heavy 9mm, and don't want to mess up my 311 punch. I have some other punches I made special nose patterns with, and that JB is hard to dig out. I could do the same thing here, but I'm fresh out of spare punches.
I might try knocking the edge off first. I did contact Lyman, and the asked me to send it in, and they would whittle me a new on if needed, send a few castings along. Every reference I see, it says 311 punch for this bullet, but it fo shizzle leaves a ring.
