I shoot alot but not 10,000 per year.You would only want to buy one of these if you used it to make many thousands of one caliber, say 10,000 or more per year. One machine does one caliber, and switching calibers requires a separate machine. Ideally, you'd have multiple reloading presses set up, one for each caliber. That may sound inflexible, and it is. It's for serious shooting.
