Bought a new takeoff .375 H&H barrel along with a used 700 Rem in 7 mag with the intention of putting together a cast boolet shooter. I've removed the original barrel and used a depth mike to check clearances and dimensions on both the action and new barrel. The barrel needs to turn roughly 135 degrees to allow sight holes to align. My question is, can I reduce the thickness of the recoil lug by the .023" needed to allow sight alignment and then run a finish chamber reamer into the chamber to increase chamber depth back to correct headspace? Trying to do this without using a lathe, but I'll take it to a 'smith if someone sees a problem with doing it as I described.
