I have a XL650 dillon and I am loading 40 cal. I have the sizing die set according to the book, there really is no adjustment, just screw the die down till it touches the shell plate, I have ran 58 brass hulls though station one, only 14 have sized, I get one here and there that will size . i have ran that sizing die down to the last thread on the Top, still can't get the brass to size. I am also using new dillon dies. any suggestions would be appreciated.
