I trash nickel plated .38/.357 because I get 5x times the split cases as from brass. Plus they are much more difficult to size. I check length on every rifle case I reload every time. I shoot semi auto rifles (.223, .308, 30-06) and they are all rough on brass. They slam them in, lock, fire, unlock, and jerk them out with extreme force. Has to be right or there can be a real problem but usually the round won't chamber and lock if the brass is too long. Safer to measure and trim.
