If you like the donor, a JES rebore might be worth considering.
If you think that a take-off barrel from a Husqvarna 46 or SR 640 in 9.3x57 would work, it might be worth a call to Simpson LTD in Galesburg, IL, as they are probably the biggest importers of used Husqvarnas in the U.S.
My Mark X in 9.3x62 has a Lothar Walther barrel and I'm very happy with it.
I've looked at the Lothar Walther barrels and liked what I saw. Did you have sites installed?
I installed a front sight strictly for the aesthetic value 'cause it is a mannlicher stocked rifle and mannlicher stocked rifles just don't look complete to me without a front sight.
I have two Lothar Walther LR Mauser barrels, a 7.5x55 Swiss and the 9.3x62, both shoot good groups.
