In looking at our customer base of the guns we have done up for driven shooting I would look at the following:

Blaser o/u 9,3 x 74R
Chapuis sxs 9,3 x 74R
Kreighoff classic 9,3 x 74R
Blaser S2 9,3 x74R

I am a great fan of the 8mm bore the 8x 57JRS is a wonderful round as too is the 8 x 65R. The 8 x 57JRS still has lots of ammunition avalible, but nothing like the 9,3 x 74R. All the guns outfitted carried a low power illuminated variable scope with 80 to 90mm of eye relief. Reticles varied but the Zeiss Vari point with the 0 plane dot is very popular with our customers. The O/U Blaser is an amazing gun and both barrels shoot to point of aim at 100m with the 285 grs Norma Oryx. I have had limited exposure to the 30 R Blaser but this seems to have alot going for it especially with 220grs RN bullets.
I do belive that regardless of the calibre and scope chosen a good set of iron sights are mandatory that are visible and fast to aqurie. The RAZ is a good one in my opinion

200 meters with a double, wouldn't try it. Up to 100 - 120 meter the 9,3x74R is first choice, or, if you can afford or you are reloader, take the 8x75RS.
