1050 With a M7 drive running 9 with a lee regular sizing die, redding competition seat die and the original Dillon crimp die . When loading 40 it's similar but the lee U die for sizing, this works for me. The 9 lee U dies shaved brass , the dillon size die busted pins to often , the dillon 40 size die wouldn't get the bulge out no matter what i did . Like said above , learn your system . The m7 stops if there is a issue with primers not coming out ( don't have this issue any more ) idk how the ammobot detects a issue at the swage station but the M7 will stop if there is a problem.
