I was always happy with using my Rockchucker to prime with. After we started having children I wanted a way to spend more time with the family. Now I sit in front of the TV and prime with a hand tool. I started with the original Lee tool and actually wore out a few of them. Now I use a Sinclair hand tool. Its a high quality expensive tool that does a good job. I'm happy enough with it that I bought another so as to have one set-up in both small and large primer sizes. When I'm using the Dillon I usually prime on it.
