Take a hard look at the 7mm-08. It's a short action cartridge, so the rifles are a bit shorter, and, therefore, a little more handy in the woods. And, a 140 gr 7mm-08 is flatter shooting than a 150 gr .30-06 or .308, and, at 300 yards, has more retained energy, so it'll perform quite nicely on the longer shots you might see in Wyoming.
