I am having a problem w/ some of my brass. There seems to be a bump above the case mouthe near the web of the case. The "bump" was consistent to a reloading ring in appearance, but does not continue all away around the case, only partially. I am thinking that this is the starting of incipient head seperation. Can anyone advise. The brass has had some loadings. This is the original brass I had started out with a few years ago when I first started reloading. I may cross section a sample piece to really see what is happening in there. Comments ready to be heard.
