Basically, take a 700 P , add flutes and I think a different trigger? , and that's it. I had the 700 P and it would shoot 7" groups at 1200 yards with r22 and a 208 amax. Basically a bone stock rifle with a thruster brake, NF NXS 5.5x22x50, and badger ordnance 20 moa rail. Eventually shot the barrel out and built onto the action with a 30" Broughton 5c throated for the 230's. AICS and a Jewell hvr. It is a HAMMER.
All in all, if you can tweak your loads, it should shoot 1/2 moa easily.
