The faster you crank up the machine the more risk of breaking s#!t. I shoot 1,200 rounds a month its plenty fast. That speed gives you time to hit the stop switch in case theres an issue. Long as I dont have to manually pull the handle its priceless. Im set up like a commercial reloading operation. I have 2 RL1100 machines Im waiting for the autodrive for one.
