well, sort of. I put 500 rounds on my tumbler, went to the pool, had lunch, and 3 hours later I had 500 like new cases ready to reload. Setup my Hornady LnL, which was set up for .223 - in about 20 minutes I had it ready to go for .45acp. Averaging 100 rounds per 15min, about 1 hour and 30 minutes later I have 500 rounds ready to go.
