Dick -
The word "tension" means "state of being stretched". So when people (other then
@fguffey) are talking about "neck tension" we are referring to a measured amount tension of the neck on the bullet. That measurement is most commonly referred to in inches here in the USA.
Example:
0.267" = measured neck diameter after sizing, but before seating a bullet
0.269" =measured neck diameter after the bullet is seated
0.002" = the difference, and the amount of measured neck tension
Now fguffey can only comprehend measuring tension in lb/pounds or in "holds".
Also has stated many times that he may be the only with tension gauges, but his gauges do not measure tension, and that he wants all the "holds" he can get.
The rest of us are referring to how much we size down the neck in relationship to its stretched measurement of the loaded round.
Fguffey may also be the only one who can't comprehend the references simplicity, and maybe the only one to do a lot of other things !.!.!
