But none of us have any idea what measures would occur on actual firing.
With FL/excess sizing, you're creating the very problems that you try to rationalize away as good attributes.
I think that if you make ammo that is actually straight, there is no need for band aids(like extra clearances) to get a gun shooting well. No need for fish tales.
And I think guns that shoot well enough with band aids, might do even better without.
It's not difficult to make straight ammo, and coincidently, to get a tight chamber fit(which creates straighter ammo) shooting well.
IMO, it's far easier all around -for well designed LR hunting cartridges.
