I pulled my Win 9mm Luger cases out of the tumbler. The media leaves a little residue behind, so I thought I would wipe it off and Inspect the cases at the same time. At the head just where the case starts to taper, I noticed a slight bulge...is this normal, is it OK to reload, or am I being too Anal about this. can any one shed some light on my problem?? Wanna kill these ads? We can help!
