Here is a conversion chart showing nose punches for Lee molds.
http://www.castpics.net/subsite/TopPunches/Lee.htmlYou can order a punch for a similar shaped bullet and usually it works quite well. If a mark is left on the bullet it is cosmetic only and does not effect the accuracy. Should you desire a perfect fit, it is quite easy to modify the nose punch with five minute epoxy. Put a few drops of epoxy into the nose punch and press a bullet into place. Be sure to clean the nose punch so the epoxy will stick, and oil the bullet so it wont stick.
