Bob,
Think trigger, fast locktime, cylindrical bedding surface, bases with 20 MOA of downhill for extended range.
Mmmm...........John you can't get one of the bases for a Sako, right?
I assumed a Sako of that type had the intergral bases and your only optic mounting options would be in ring selection.
With 20 MOA of downhill on a square action and an optic with a proper amount of travel you will be able to dial to 1 mile running the 105 VLD at 3050fps in the thin air around a little town called Medicine Bow.
One 20 MOA revolution will get you to just over 950yds. Such rifles are pretty useful.
