It makes swaging easy. Saved a step in the brass processing. I can prep 1200-1500 rounds per hr. My budy uses a dillon 650 to size and trim brass then he had to swage all the brass on the super swager from dillon. I am able to run my brass thru my Dillon 650 once to prep then once to load. I dont have to handle each piece of brass to swage. Just put in in the case feeder and go to town. Great product!
