Before I toss in the towel on this thing I thought I'd ask here. I have an older Lee Auto Priming hand tool, with the round holder. It doesn't have much use and appears to be in very good condition. Yesterday however it developed a problem. It will not fully seat a primer any more. It partially seats them just far enough for the shell to get stuck in the shell holder. From what I can see there is no wear or broken parts, and nothing which would interfere with the primer seating. If anyone has experienced this or has a fix, please advise, before I replace the tool. They offer replacement @ half off plus shipping, but I might go a different route if I can't fix this one. TIA.
