Thread: Setting Back A Barrel

In a post to sell a rifle the seller said something to the effect that the barrel has been set back X mm, so I asked Google what this means and it said:

"Set-Back Barrel – This involves a gunsmith cutting off around 1” of the barrel (on the chamber side), then re-reaming the chamber. This essentially removes the part of the throat just forward of the chamber, which is where primary throat erosion occurs. You may lose an inch or more of length in the set-back process, but can dramatically extend barrel life"

Has anyone here set back a barrel and can advise costs/benefits, perhaps indicate which gunsmiths provide this as part of their service?

Cheers
