I have an NOE 44 cal 280gr 2 cavity bullet mold. It drops it's bullets right at 280 gr from my scrap WW. Bullets drop from the mold at .434. I then PC & size thru my .430 sizer. This sizing swedges the driving bands & narrows the crimp grove considerably. I am not confident , even with a heavy crimp, or what crimp I can get , that the bullet will be held in place during recoil in my revolver. Can the crimp grove in the mold be enlarged by about .005 in depth & with? The bullet is wonderfully accurate & drops from the mold easily, so am hesitant to sell & replace with a new slightly smaller dia mold. BAttachment 287068Attachment 287069 Bullet at the left is the 280 gr, & bullet to the right is another of my 44 cal with , as you can see a much more generous crimp grove. If all else fails I may sell.
