I believe that Lee says not to use Federal primers in their auto prime tools for this very reason. That said I have loaded tens of thousands of Federal pistol primers using my Lee Auto prime and never had a problem. I do however always wear safety glasses.
I have had the odd primer feed at an offset angle and begin to jam when using an Auto Prime but as soon as I felt something was wrong I stopped and cleared the primer. One time when it jammed I took it outside, removed the other primers from the feed tray, put on a welding mask and squeezed the primer flat - just to see if it would detonate - it didn't.
I'm glad Scrumbag is okay!
