7mm Mauser loads

Searching for acceptable loads for classic hunting rifle in 7mm Mauser. Rifle built by Dennis Olson in Montana. Nice rifle but not having much luck finding a load it likes. Suggestions?
I have had good luck with 139 grain Hornady interlocks and h4350 slightly downloaded in a sporterized 1895 Mauser. 154 grain SST's with h4350 showed promise in one of my 98 Mausers but haven't finished load development on that one.

Was hoping for something in the 150-170g projectile, but I have some lighter 140’s that I will try. Did you like the performance with the H4350?
