As far as competition shell head holders. OK if you insist. I can see the theory behind it but your press will jam the butt of the case against the face of the shell head holder no matter what. Spring back??? That is just the tolerance built into the shell head holder rim slot. It's like backlash on a gear, when you reverse the direction there is a slack of a few thousandths of an inch. It is designed into the gear to reduce drag. As far as the cartridge case goes, it won't make any difference in sizing. It just means that the sizing die will release the case a hair later.

I don't think you're quite getting it. Making a difference in sizing is exactly what they do. The shell-holder rim bottoms against the bottom of the die with all of them. The distance from the face of the shell-holder to the rim (and therefore to the die) is what varies.
