I recently got a Traditions 32 cal Crockett and trying diff combos to shoot....would a 310 ball with 20 patch be the equivalent of a 320 with a 10 patch? Would the minor weight diff be of any value? I generally shoot spit patch as I'm shooting at paper and so far no patch has burned or shredded. Doesn't a 310/20 combo work better than a 310/10 for the sake of velocity?
