+3 for the VP15 (PT1215) from Ballistics Products. An excellent fitting wad. Although they are not on sale any longer. I didnt get very good results with the Fed wads or their clones. With the 12S3 I got dished crimps with 1-1/8 oz and I could not fit 1-1/8oz using the 12SO wad. I did not try any other wads but these.
