What do you own?
I have a #1 in 25-06 and a WBY Accumark in .257 WBY that I consider perfect for my style of hunting..
These are my first choices as well except a M-70 fast twist 1-8" .257 Wby. and a Ruger No.1 with a 28" barrel 1-10" and another M-70 with a Bartlein 25-06 Barrel 1-9" twist. Two others are the 6.5-06 AI and 280 AI.
Really anything from 6mm to 7mm Rem Mag. is ideal. I don't like more recoil than the 7 mags as you may be shooting from an awkward prone position. The 22s from 223 on up are also viable but if traveling a long ways I would only go with the bigger 22s and longer bullets as you can almost count on wind being a factor.
Wyoming is where a lot of the using a plow chain (or insert any heavy object) for a wind gauge jokes come from. Even the 25s with conventional bullets will be affected, less so for heavier VLD type bullets.
