Will a new cartridge chamber? If not, you need to clean the chambers. If it does, you could run the offending rounds through a Lee factory crimp die. I don't think you can just pull the decapping pin from a normal sizing die as it will squeeze the bullet too much and you'll loose neck tension. Anyway the FCD would be much faster than pulling several boxes of bullets.
