So as I am getting back into reloading and getting count of my brass and such I come to the final count of around 7000 pieces of 9mm brass. I remember in my teens this felt like nothing but one torn rotator cup later I will feel the burn. I will be using a pro1000 to resize the brass. I have watched videos of Dillon 650 being hooked up to electric motors with what I assume are gear boxes and cams to create the operational stroke. I get that only trial and error will generate any success, I am hesitant as to what power source to use as I already have a AC electric motor with a gear box(uncertain of theRPM) and I am leaning toward a air cylinder with limit switches. What are you thoughts on a air operated pro1000?
