I've been reloading for a few months, but up until now I have only loaded .45 ACP. Last week I decided to try .40 S&W. I noticed bulges in my brass while loading my first few rounds. Since it was range pickups I figured it was just a few cases nearing the end of their life. Long story short it wasn't. I'm using Lee 40 S&W dies and the de-priming/full length sizing die is causing these bulges. The picture below the case on the right has the bylge the one on the left doesn't. I hope you are able to see it, the bulge is about 1/4 inch from the rim. You can feel the bulge. Everything passes the plunk test ok, but I haven't shot any yet. Should I be concerned or should I just shoot away?
