I went to the range and got some brass for 9mm. I had found alot of it and I had check them. A few of them have a small bulge down near the base of it but before the extractor point. when they have this bulge I look at the primer and its not indented but it is protruding outwards. I put it in the resizing die and it takes this bulge away and takes out the primer. do you think it safe to use?
