I know of one competition shoote who had the best possible solution, at least he thought so. he would take his brass after 6 loadings and scatter it at the range. If he had old magazines, he'd have given them to someone he didn't particularly care for. As he said, there are ways to compete that don't include self-improvement.
I didn't particularly care for that philosophy. I never did figure out if he was just kidding. we didn't talk much, and this was thrown out in an off the cuff conversation just once.
