The RCBS bench priming tool is the best.
I have a LEE hand priming tool and it is the biggest P.O.S. of all the reloading equipment I have. I use it for reloading at the range and I absolutely hate it.:mad:
The only reason I can see that the LEE has such a following is that those that use it have never used a good priming tool, so they just don't know any better.
