Curious if the rifle is the 1909 or 1935. Seemed a fair number of 09s were rebarreled with Liege proofed barrels, still in 7.65. Matching bolt number on 1909s is hard to find so if present perhaps worth getting back to 7.65x53. I like the 7.65 round but as a shooter I appreciate the convenience of 308. Good luck.

I mentioned it in my first post but it may be worth repeating.
Lots of military issue Peruvian Mausers in 7.65 Mauser caliber were simply rechambered on their orig 7.65 bbls to 30-06. So the groove dia in these 30-06 conversions is .312 Conversions were done post WW2. I've read it was done by the Peruvian Govt and also some say by FN for them. We supplied the ammo post war.
The bbls show their orig Belgian FN mfg proofs and other period mfg markings. If the bbl is orig to the rifle the serial number matches and most do. The front recv'r ring is notched. This was done during the caliber conversion to allow smooth stripper clip loading of slightly long(er) GI 30-06 rounds into the mag box. The rear bridge was generally hand stamped ' .30 ' to note the caliber conversion from the orig Mauser round.
The Peruvian crest remains on the top of the ring.
It could be one of these 7.65Mauser caliber conversions to 30-06 caliber that has since had a .7.62NATO insert put into it for convenience of ammo supply. Those inserts were very common for M1 conversions to NATO cal at one time and 'the thing to do' with a crusty old 30-06 Military bolt rifle,,,who wants one of those after all.
If this is what you have, Removing the NATO cal insert would leave you with a 30-06 chambered bbl with a .313 groove dia bore of the orig bbl.
I have one of these Peruvian Mauser conversions to 30-06 here now, in bbld action form. Wondering what direction to go with it. Perfect bore but a .312 of course. FWIW, (Some of?) the Peruvian Mausers have the 'reversed' flag safety positions on the bolt as well. FIRE position is the Safety laid over to the right side.

Kutter, Your comments are well taken but pertain, I think, to the 1935 Model. I should have said earlier the rifle in question is a 1909. CJF, Yes the bolt is matching which is the major factor in this project.

Mike, I think he's decided to have the chamber bushed again but this time over the length of the case body. When the work is done, I'll report the outcome.

Bill, Based on bad experience with someone else's bushing job, I recommend the following two things be insured. Be sure the cartridge case neck extends past the joint, so that obturation keeps high pressure gasses out of the joint. The second is to pull the bush into the barrel with a rod threaded on both ends with nuts and washers to keep everything tight until the glue sets or the solder cools. Bushes, pins, dowels etc. are pretty bad to back out of holes while waiting for glue to set/solder to cool; whether due to taper, trapped air, pressure from expanding gas; movement must be guarded against.

Mike, That sounds like good advice. I'll pass it on.
