Good Morning, Hamer,
Your choice of cartridge for both applications is excellent. The .308 Win will reliably kill all North American big game. It's an inherently accurate cartridge that's entirely suitable for target shooting. However, a rifle for one application is not always suitable for the other.
You might want to consider buying two rifles. I can tell you from experience that a granola bar is heavy at Rocky Mountain altitude. Hence, I'd go with a lighter weight rifle. The first shot at a big game animal almost always determines outcome. Put your first bullet in equipment necessary for topside oxygenated blood flow, and all living big game will hit dirt.
Dedicated target rifles tend to be on the heavy side. I wouldn't want to carry a heavy rifle up & down high ridges of the Rockies.
I have no experience Barrett or Steyr. I do have experience with Sako. I own two that'll shoot .25" at a hundred all day long, often better, with hunting loads I've loaded using standard dies. I've never used tricked out target dies and ticked out target bullets. Hence, I'd recommend a Sako. However, an accurate lighter weight rifle will work if you can count on its first shot as destroying necessary vitals; e.g, heart and/or lungs. Nothing living remains in that condition without topside oxygenated blood flow.
