Rapine will make you a nose punch if you call him. The other option is to take a .50 cal nose punch and some epoxy. Mix up some epoxy and fill the cavity in the nose punch. Put a coat of wax or resizing lube on a bullet, and press it into the nose punch recess. Be careful and get it straight. Leave it in place until the expoxy hardens, then remove. You now have a custom fit nose punch. If you change styles, you can do the same thing again, so pretty inexpensive this way.
