om im going to attempt to make a HP mold. any tips???? looking at taking a 230 grain RN .452 bullet mold and making it happen. what size of HP hole? should the pin be tapered where it goes in the bullet? any tips on centering this thing? im assuming i should drill from the bottom into the bullet. not from the bullet out the bottom of the mold. any tips or any threads or how to's point me. thanks and if it dont work all im out is a vintage lyman mould right..... -chris
