I've noticed and thought about what you are saying Nuggin. I posted something about it a while back but don't always explain myself well and no one ever responded about it.
In my experience, the brass gets bigger than the chamber as it is extracted in a gas gun. I have to bump it down to get it to fit back in the chamber.
I personally played with this in a 223. I sized the brass, tried to chamber, resize, chamber, etc etc until it fit and extracted smoothly. I then bumped it a a few thousandths more. The rounds fit in a wilson gauge. The case is always bigger than the hornady piece.
It's extreme in my bolt rifle. The chamber is much longer than the hornady piece and I only bump the fired brass .003" when resizing. If I used the LNL it wouldn't be anywhere near where I need to be.
