Unfortunately your preconceived notions don't match reality.

Read the post by steve4102 in this thread and make note of what Sierra says - the bullets tended to move FORWARD an average of .003" with extreme cases up to .007". There are two methods to keep the bullet from moving in the case, crimping and neck tension.

You're not incorrect that bullet setback is a thing and it's to be avoided. To the detriment of your argument, however, it's more of a thing and far more dangerous in autopistols than rifles. You know what will raise chamber pressures faster than a bit of bullet setback in a centerfire rifle cartridge? Having your bullet jammed into the lands. Yeah.

Re: neck tension and measuring diameters, you're technically correct but I'm talking about STANDARD PRACTICES. Don't like it? Want to be a pedant about it? GREAT! But guess what - no one cares. That measurement is talked about all over the place. No one is talking about measuring bullet seating or pulling forces, which can be done (and is, by competition benchrest shooters) but is not cheap. Measuring the before/after neck diameter is an accepted practice. Deal with it.

Again, you're tilting at windmills with your case neck concentricity (that's the word you're looking for, BTW) argument. It's not the point of this thread and it's not the concern of the OP. In fact, I don't even know why you're arguing with me, other than the possibility that you've got a bug up your ass and you just want to argue. You even say it yourself:

And in any property sized case it should never be an issue.

Yup, you're proving my point. In a properly resized case it shouldn't be an issue. Anything else you'd care to be an ass about, or can I get back to the OP's concerns instead of addressing your delusions and misconceptions?
