First I would be very happy to get some more information about this double rifle, I can´t find anything on the web but perhaps in this forum?
It´s a post war Sauer & Sohn rifle in 7x65R, probably from the 1960 era? According to the former owner it´s regulated with 173 gr RWS.

I´ve tried several loads with 170 and 175 gr bullets (woodleigh, nosler partition, speer GS, norma oryx) and different Norma powders (MRP and URP) without satisfying groupings (about 6" and up). I also tried the Sellier & Bellot 173 gr SP that gave about 4" groupings at about 90 yards, with the scope on. I´m new into double rifles, and perhaps I´m doing wrong, or have to high expectations - but I´d like to find a load with a premium bullet (not the S&B) that shoot about 3" at 90 yards....perhaps not possible?

I appreciate all kinds of information and advice here!
Thanks
