Can you rechamber a .270 WSM to 6.8 by shortening the shank/chamber end and running a finish reamer?

I contemplated building the .270 WSM in 2012 but went with the .270 AI instead, partly due to the brass shortage at the time. In addition, it is my first Ackley. I prefer the .270 WSM over the 6.8 Western, especially now that the brass selection is significantly better. My .270 AI is 1:8" (the fastest twist available at the time); 1:7" is the way to go.
None needed to fire form in 270WSM

There is no "should have"
Glad the banter sparked thought. Here is an additional idea if you reload.
With a new barrel, you can get a faster twist, say 7t or 8T, and stay with the 270 WSM and use all the same reloading tools and supplies.

I would say yes by taking of about 1/4" of tenon rethreading a rechamber with a long throat. I just don't see any benefit in doing so. But it is your rifle and your dollar
This would be the route I would go. I have rifles in .270 WSM and 6.8 Western. The better bang for the buck is more free bore and a faster twist barreled 270 WSM.There is no "should have"

The reason that they are 2 different "Calibers" is the twist rate of the barrel. If you want a 6.8 - change the barrel.
You can load the heavy bullets in the 270 WSM cartridge but the twist rate is designed for the 140 through 160
grain bullets.

Exactly this. Just get a 6.8 Western and be done with it and keep or sell the .270 WSM--you can never have too many guns and no reason to mess up a perfectly fine .270 WSM
. My 6.8 Fierce Carbon Rage has a 1/7 twist barrel specifically to handle the 165 NABLR, 170 EOL and 175 STGK bullets. You won't really have a 6.8 W without that fast screw pipe.
I didn't really know, just an assumption based on standard twist rate for .270 WSM.
the 5 degree shoulder and couple thousands dia. is so small it is no different than fireforming any new brass to fit your chamber. to be honest the difference with factory ammo is minimal between the two that for short action and high bc bullets the 6.8 is the better choice. the only advantage the 270wsm has is reloads on as long action and even then, the advantage is minimal if reloading both to the upper limits.
Agree to an extent. If you build a 270WSM on a long action (as I did) more than likely one would modify the chamber with additional freebore to take advantage of the extra case capacity. Still splitting hairs though.
From what I understand a .270 WSM with 175 gr bullets will not fit in a short action's mag box or feed from it, while 6.8 Western with long bullets will fit and feed (isn't that the reason they developed the 6.8 in the first place?).
I originally asked because I've seen several M70 Classic rifles in .270 WSM that I've thought of picking up, but no point in rechambering a 1:10" barrel.
