gee, i'm getting old but i have a 3 hole lee turret press that should auto index but inthe 25 years i've had it, i've never gotten the pieces of sh!t to work properly, despite many hours of tinkering and cussing. so, i've always used it as a rotable single stage press.
however, have recently upgraded it to the 4 hole turret which has been working great with respect to the auto indexing. i see that lee completely redesigned the ratching mechanism on the 4 hole upgrade kit which seems to make a difference.
so, if you have a 3 hole turret press, get the upgrade 4 hole kit.
hope this helps
