Why did Remington Short Chamber all these R700 barreled actions from the custom shop and how did they finish them off?

I watched a worker finish reaming 700's and it was done as described. The barreled action was held in a vee block arrangement, the reamer inserted from the breech and chucked at the muzzle end. The bolt was inserted behind the reamer, the machine was turned on, and when the bolt handle dropped, the chamber was done. Given the number of eccentric chambers which were produced, this may not have been the best system ever. Interestingly enough, some Swiss Arms barrels I looked at had the chambers forged right along with the bores, with no reaming, and they were superb. No marks, even under magnification. The barrels are very accurate, by the way.
The Illion plant is an OLD facility. Even the Cincinatti cnc machines, dedicated to the Mag 10 shotguns, were far from new when I was there. WH

so the reamer was “ proper” length to get headspace close? good info here i just saw - thanks

They are the ones actually fulfilling the orders from PTG. Here's a snip of the conversation. It doesn't show everything, but you can see the gist of it. View attachment 1278915

Thanks — i just wonder if the rem custom shop was leased. i thought rem owned it and it would have been shut down when they shut down. mabie someone else bought it?
