Here's a good article on bullet pull force:

Bullet pull forces determine the pressure needed to push bullets into the rifling. The more uniform they are, the more uniform velocity is.thanks for the link Bart but why should I care about bullet pull values?
Seating force is usually different (higher) than bullet pull (or push) force needed. The case neck diameter gets expanded bigger.
Bullet pull forces determine the pressure needed to push bullets into the rifling. The more uniform they are, the more uniform velocity is.
No.Bart, you control inside/outside neck dia by bushing or expander If the start is the same won't bullet pull be the same?
In short, polish and clean the inside of your case mouth and bullets.
It depends on how hard or soft the brass is. It'll be less with soft brass.Reread the chapter by Litz and starting to wonder exactly how much of the effect of .001 neck tension would make.
How would you measure your hand tension on the broomstick in fractions of an inch?
@UncleNick - that's great but in the real world most of us do not have the training or equipment to determine real neck tension. For those who want to then clean the brass to bare metal, measure the thickness to .0001 and here is the math
