Got my Lee Classic Turret Press Sat. for my B-day. Set it up and loaded about 100 .357's. Went to range and shot them all. Now I notice my cases have developed a couple of scratches after I run them thru the Lee resizing and de-capping die. I took the de-capper out and sprayed a little clp break free on a q-tip and wiped the inside down. That made a noticeable improvement, but I can still see a couple of light striations.. Any advice on how to clean resizing dies or is it ruined? Should I stop using it and buy another?
