Call it what you want, but most folks identify Neck Tension with what I describe.You can't.
What Rick described is INTERFERENCE fit.
And seating forces are not tension either, but seating FRICTION.
Neck tension is the gripping force applied to an area of seated bullet bearing (in PSI).
We currently have no means to measure it.
I hear most people shooting for .002-.003 interference but as long as I can push a bullet tip on a loaded round against the bench as hard as I can and it doesn't move, I'm usually happy as long as your dies are not overworking the necks of the brass.Mike, so is there a certain amount of interference fit I should want?
The amount I want is 1thou under cal after spring back. This ensures I have full force diametrically, and even that little will be upsized with seating for 22-26cals.Mike, so is there a certain amount of interference fit I should want?
I’ll give you a hint of WHY what we do in regard to IF changes with length of neck sizing, it is the AMOUNT of friction on bullet release.Holy smokes, Magnum Maniac, you are so far ahead of me that I will never catch up to your level. Thank you for the info. It might take the rest of my life to try and understand it.
