About 5 years ago I got a great deal on Super X Win Mag 510gr SP's for $30 a box. I only bought them because I was told that they work in the Lott with out any problems. I shot them off and had no problems. Now the rub, I just came across the empty brass and was wondering if I could size and seat using my Lott dies. Can anyone please shed any light on this subject? Thanks in advance.
