I use my Rockchucker for all decapping and all the assembly steps, except primer seating, for load development and for bottleneck rifle rounds. I find it to be rock solid, makes very accurate rounds.
The only thing I don't like is the stupid tray to catch the spent primers. Usually, more than half the primers accumulate outside the tray, in all the crevices around it and on the floor.

For bulk loading of proven pistol rounds, I use a Hornady LNL.
