Your build should be a thumper!
You might also look into E.R. Shaw for your barrel and work. I've bought 2 barrels from them and absolutely love them!
My 284 Win barrel, 24" polished, blued, 11 degree recessed crown in their 1.5 contour for my Mauser build was $272 shipped to my front door.
Does make for a HEAVY rifle though. 10lbs scoped, no ammo.
You can always thread the barrel for a brake. Another option is a recoil reducer in the buttstock. Essentially a mercury tube with an oriface in it to control the flow of mercury.
They are popular with shotguns, and some of the harder kicking rifles.
I gotta admit, i was reading through the posts thinking "YES! a 25-06 barrel!!! " lol
