Per my previous mauser thread, I have an interarms mark x action I was originally going to build into a 308. Going so far as to buy a heavy barrel from green mountain barrels.
To save myself from buying another barrel, would a gunsmith be able to ream out the chamber on that 308 barrel to a 300 wm chamber?
