For example, I just got a 6mm barrel and 6BR reamer and was thinking I'd put that on the M70 long action now and later get a short action 700 to move it to. Obviously the headspace would need to be reset. But, matching the 700 threads now would make that more feasible.
To your point, that may be overly optimistic if the subsequent 700 reciever threads have to be cleaned up and open up a little in which case, it won't be easy to get a good thread fit from the take off barrel anyway.
..plus the length of the threaded tenon doesn't match up either between Win and Rem.
Whether we're talking about the barrel or reciever, once you take off metal, you can't put it back on.
I am not a proponent of switching barrels even though people do it. They have to be head spaced
with each barrel and as you take one off and screw the others on you lose your head space and
thread fit eventually.
And every time you take a rifle out of the bedding it deteriorates the fit and will loose accuracy.
I like the 1 1/16 16 TPI and I see your point but as you said the tenons dont match anyway.
What I was refering to was cleaning up the threads maybe .010 thousandths and fitting the threads
of the new barrel to the receiver (The tenon threads would be 1.010).
If you use takeoff barrels you will not get a good fit "EVER" because they are all different sizes
due to the quality control at the factory and the acceptance tolerances.
If you are looking for ultimate accuracy, It takes all of the elements in perfect conditions and
the less you disturb them the better. (This is one of the reasons that benchresters glue the
barreled action to the stock).
The only system that I would use to switch barrels is the Savage with the barrel nut, And when
I rebarrel a Savage I do away with the barrel nut because of thread fit and extra components
that can lead to accuracy problems each time they are taken apart. (Two many variables).
Sorry for the long winded explanation.
Again this is just my opinion based on my experiences trying to ring out all of the accuracy
