I am specing a reamer for a 7mm cartridge. I have some Cauterucio bullets to shoot and these bullets measure .285. I was wondering if I need to make my lead at least .285 to shoot the Cats? Will I be able to shoot other bullets like Berger, JLK, Sierra without any ill side effects like loss of velocity and accuracy? If I spec the lead for the other bullets at .284 will I be able to shoot the Cats without experiencing extreme pressure? Will I even be able to chamber the Cats?
