Thanks to all West Coast Bullet fans! I just recieved 1000 200 grain SWC's and they look great! I have a newbie question though. When I measured them at their base they were .451" like a jacketed bullet rather than .452" like the copper coated "washed" bullets I have been reloading from National Bullet Company. Should I be using "jacketed" reloading formulas or can I continue with the same lead data I have been using?
