Lee's work fine until you get a .416 Rigby. Then the case will not go into the tool. The plastic opening is to small, the shell holder fits fine. Just molded too small. Just bought an RCBS but haven't used it yet.
I've been useng a RCBS hand priming tool for years without any problems. Awhie back I see that RCBS made some changes. I never heard any complains about the old ones but so far folks dont seem to like the newer version all that well.
