Gopher: Consider a Valmet/Tikka o/u combo, available as double rifles or rifle/shotgun; I have a Valmet 12/.308 set that does very well. The barrels have DIY screw adjustments for elevation and windage. Russ Gould at http://doublegunhq.com/ is listing several Valmets right now, including a Valmet 412 that could be set up with your choice of rifle barrels. Scope mounts are available too.
