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.
