Tophernj;
I'm going to go t'other way. Because you've stated that the gun will be primarily used for target work, and size/weight is not a primary factor, I'll suggest you look at the CZ550. That's a full sized Mauser action that would work beautifully for the 6.5 X 55mm Swedish Mauser. If you want accuracy, the Swede is known for it, with mild recoil to boot. Again, for your stated purpose, the larger gun is going to ride the bags better and it'll also reduce perceived recoil.
I'll also suggest that you pay no attention to the short/long action arguments. There are perhaps about 150 people competitively shooting in this country today who are good enough to prove that they need the exceedingly slight advantage of a short action. If you're literally not gunning for a spot on the Palma team, Olympics, taking the Wimbledon Cup, etc., it's all rhetoric. Given that you and your smith can produce the gun & have the accuracy skills on the trigger, the Swede is fully capable of giving outstanding accuracy to any remotely reasonable range.
