Re: I have a Reloading problem I need help to solve.
Yes the shiny marks in the pic is normal for a full length die with a belted case, you my friend are on the verge of a nasty case head seperation, trash that brass. Also Gary reccomended the innovative tech die, this is a wise investment for belted cases, allowing you to size down over the belt as well, use it every 3rd or 4th loading and it will give you longer case life. Also if you want to neck size, which is my prefered method for bolt guns, get a bushing neck die, the shoulder bump deal with a FL die works, but you are still squeezing the case walls back in, just not as much. Do it right, do it once!
