You can, but it MUST be set back. It has to do with body taper.
Years ago "gunsmits" were taking BR reamers, cramming into BR chambers, and "kapow", instant Dasher status.
Till the shooters started sneezing cases left and right due to the webs being stretched out like the Homecoming queen. The tool (chamber reamer) must be specific and the barrel needs to be set back so that it has fresh material to catch everything back up with.
Insist on this. It'll save your face and your wallet from a beating.
