I'm working up a new load for the 325 wizbang, 180gr TSX's. Today I loaded 3 sets of 3 rounds with different powder charges. On the last set of three one of the bullets was much more difficult to seat in the case than all of the others. All brass is new winchester, full length sized and trimmed. Should I be concerned about this one round possibly generating higher than normal pressure? It is one of the 3 loaded at max. But, I'm not sure which one now. I'm thinking about just pulling all 3. Am I being paranoid for no reason??
