I load sts--Goldmedels---AAAs---gunclub---estates on my Dillon and make no changes except for the wad needed for each hull---It just keeps on Ticking-
I'll give one tip---I cut a grove in the primer drop tube so I can make sure I can see all the primer [email protected]
Wen I purchased my Dillon used it would not seat Winchester primers into My STS cases consistently, I tried STS primers and had no problems. My Mec 600 jr. would seat Win. primers in the STS cases without a hitch. No idea why, As I had a lot of STS cases I use STS primers and am happy. Maybe Dillon can answer the question for you.
