Just sat down for the first time, with my Lee single stage press and 100 once used .40 brass, deprimed and then reprimed them. I made sure I used the resizing die when I installed the new primers. It was then I noticed that some were rather fat in the middle, not at the base where Glock's infamous lack of support is supposed to be. Assuming they'll drop into my barrel OK when I check for fit, should I worry about loading and firing these? Wanna kill these ads? We can help!
