With 9 primer tubes ready to go and one tube preloaded, I can easily achieve 1,000 9mm loads within an hour with the 650 and case feeder. That's of course without screw ups of any kind, and without stopping to check weigh powder or measure OAL. To be honest, I don't weigh powder very often since every time I do it's consistently right on to the 10th of a grain. But every case does get a visual check after it leaves the powder check station while I seat the bullet with my left hand. Once you're used to it, you will crank out a round basically as fast as you can fully cycle the handle. Each crank doesn't take much more than about 2 seconds once you get some practice.
