I have one of each the Dillon roller and the stock ball on two different presses. To me they both have good and bad points. I like the way the ball feels settling primers. But for long sessions the roller feels better after a hour in.
West central Illinois. Just a backyard plinker. Shoot most pistol calibers along with 223 and 22-250. Just started reloading last year that's how I found this sight.
