I posted this to show the current relay on a PW Autodrive, which a lot of 1050 people are using. I have a Mark 7 1050Pro that I use for everything else but for .32 and .38 wadcutters, this has no competition. Mr Bullet Feeder and the like can't process the hollow base wadcutters, this can because I use a no longer made bullet feeder made by MA System that uses a "Finger" style feeder. The great think about the Current limit relay is it gives the dumb PW Autodrive a cockroach size brain.
