So me and a buddy shoot a lot (500-1000 rounds a week) and we have been loading 9mm with single stage presses. While we can really crank out rounds quickly for a couple jimokes on single stages (200-250 rounds an hour) we are getting pretty tired of it. Our hands get raw and tired from priming and we shoot enough that a progressive may be worth it. Has anyone used a Dillon 650 or a Square Deal B? The SDB is about half the price of a 650 and that means a lot to 2 broke college kids. I've been reloading for almost 10 years now, so I like to think I know what I'm doing. Any input is appreciated.
