MY 1050 is about 3x as fast as my 650 was. primer seating on the down stroke is a wonderful thing. The bullet feeder also helps a bunch. Its litterly keeping things full, and cranking the handle. Its almost mindless. yes you still have to pay attention, but there is no real "hands on " tasks like loading a case into the shell plate or placing a bullet on the case mouth. other then filling things. I only check about every 50 rounds, buy wieghing it and putting it in a case guage. if it specs out the bin getts dumped in to the box of loaded ammo. me sorting thing by wieght before hand helps a bunch.
