The inside diameter of the case neck measure right at .310" after resizing. Ironically, the chosen projectiles have an outside diameter of,  .310".
After priming the cases and charging each case with my chosen smokeless propellant, I seated each bullet accordingly. Every bullet has sufficient "projectile-to-case" tension without the use of a crimp.



A .310 neck ID and a .310 bullet OD? Are you super gluing the bullets in the neck? LOL

No problem.
I think the second one was limited to 2-groove bores that were worn?

.3100 neck and .3100 bullet gives a slip fit. Try measuring the neck ID with a pin gage if you have them, it must be smaller than the bullet, otherwise, you could push the bullet into the neck with your fingers. 

I don’t use less than .001 interference, usually go for .0015 to .0020 interference to get sufficient neck tension for magazine feeding.  .001 interference is OK if single shot feeding.

It takes just over 18 foot pounds of force to unseat this particular bullet Geoff.  The .311" to .312" projectiles require just 20 foot pounds of force to unseat them from the cases. 
Not truly interested in going above and beyond by using a pin gauge. I trust my digital calipers and my .310" neck expander.
The point I was making here is in reference and regards to the issue with two gentlemen not being able to get their bullets to hold to the case neck without using a crimp and something internally out of specification with their Lee made full length resizing die.

If your getting 18 lbs of force to push the bullets into the case neck then you have about .001 interference. I assume you mean pounds and not foot pounds.  Foot pounds is unit of moment or torque. .002 will give about 40 -50 lbs of force to seat a .30 cal bullet, but this value does depend on if the necks are lubricated, dry, polished or have residual powder fouling in them.  I experimented with this using an arbor press with a force measurement pack to seat bullets and measuring neck to bullet interference with pin gages. Annealing the necks reduces the force to seat a bullet. 

Lee is a good company to deal with, if you have a problem with their dies, they will make it right.
