Been reloading since mid 70's and only reloading 9MM past few years and bought some once fired 9MM brass. I have two different type cases, as seen in picture. One on the left has like a little brass (colored) ring, and the other does not. Primers dont want to go into one on left, have to use a little reamer tool and round edges a little and primer will go right in, case on right, I have no problem with primer. Case on left has WCC 98 on it, on right has Win 9MM Luger. What do you know about the cases, especially the one on the left. Thanks!
