George P., I deliberately ordered one of my first MP molds with GC because I still thought I needed it for plastic-coated bullets (which is completely wrong). I never put GC’s on it and always got good results with it. Years later, I thought I had to buy the same mold from Miha without GC because the bullet base bothered me visually. I can assure you, there is no difference for me in the precision between the two. Surely you will have found out by now – it also works perfectly with this bullet rear! Have fun with it and greetings from Germany Michel ��
