I started out reloading on a rcbs rockchucker this was the only press I owned at the time. Rifle or pistol all were done on that press. When I started fooling around with cast bullets the mean green rockchucker was still there. However when I started shooting steel plate matches I also started with the rockchucker, but it seemed like almost forever to turn out 300 rds for the match. On the advice of some fellow shooters
i bought the dillon 550 for my 45. Instead of spending 3-4 hours getting 300 rounds ready It was more like 1.5 hours. Hey I'm not as fast as everyone. So about once a year I take it apart clean and lube and away I go. The single stage is slow, but mistakes are easily spotted and corrected. I prime separately before the cases go into the dillon. I use that time to better inspect cases and any that are messed up get binned. Now the rockchucker has been replaced by the lee classic cast and still is used for cast bullet loading and rifle cartridges. Frank
