That's usually not good right at the muzzle.
If there was that much stress in the very end of the barrel that turning it down and threading it would change the ID Diam. of the barrel on the end the barrel would be junk to start with.

Are you talking "in Theory" or have you been able to actually measure the change?
I know that My 300 Win. Mag would not shoot as well with the Holland Break as it did with out it. It went from shooting 1 MOA and under to 1-1/4 MOA with it installed. Never thought about changing the load to see if it would shoot the way it did before the break was installed.
When Holland of Powers Oregon installed the break they re-crowned it.
I shot one shot from it in the field at a nice buck and that is the last time I ever used it. No ear protection. WOW did it ever hurt
Can I say my ears rang for about a week after.
It has been a safe Queen ever since, but will be back in action soon as I am having the break removed and re-crowned.
But not by Holland's.

With all I said above. I have to add that the wife had a Remington 30-06 that Hollands put a break on the same day they did my 300 Win Mag. Exact same style.
And I must give them credit as it shot just as well with the break as without it maybe a little better. The wife does not have the 06 as she gave it to one of our son in laws. She has shoulder problems and can not hold it up anymore.
