I will be shooting 300 SMK & Bergers (when they are fixed )
I was thinking 1-10 & at least 30"+ long.
This will be a long range plinking rifle and as such I'm not worried about the weight & want to get max velocity.
I have a 338 Edge for hunting with 1-9 & 30 inch barrel, 2850 fps.
My recommendation would be pretty much as you have described= a stainless barrel 30 to 34"
long, In a #7 or 8 taper or contour (Around .900 dia at the muzzle) twist should be a 1 in 10''
with the velocity you will get and a 3 to 4'' shank for strength where it is needed.
I like the 8 groove barrels for heavy bullets (Easier on the jackets when engraving).
Put a good 11 degree crown on it and the break would be optional but if you shoot a silencer
thread it for both and Enjoy.
