Lee Collet die set up = A great die but ignore the instructions. The instructions are correct but often leaves people scratcing their heads. Or pressing to hard and pushng the alum. top out of the die!
Instead, put a fired case in the shell holder and raise the ram full height. Screw the die down as far as you can by hand. Then lower the case and turn the die down a bit more, 1/8" is usually plenty. Again raise the ram, full lever travel, and "size" the case. Check to see if a bullet still slides in easy, it likely will. Turn the die down another 1/8th OF A TURN
, NOT 1/8th inch!, and try again. Keep it up until you can't insert a bullet into the fired case neck by hand
. That should be enough, lock the die ring and size your cases. (Do NOT attempt to adjust the Lee die without a case in it, it will likely jam up)
Trying to be concerned about whether the lever "cams-over", or what 20 lbs of force on the lever feels like, is too indefinete. But attemping to hand seat bullets after full lever travel isn't indefinent, it works ever time it's tried!
