There are alot of good choices, 7mm, 270, 308, ect... The 30-06 is probably the best, you can find ammo almost anyplace and it is the classic all around rifle.
If you want a magnum and can handle them great. I know how to stalk, but sometimes you run out of cover and it leaves you with a long shot at a trophy. It still takes skill to make long shots, but you are shooting flatter with alot more downrange energy.
Personally I use a 30-06 around home, and a 300 remington ultra mag on trips. I have limited knowledge of the area, and less time to hunt, so if I see a trophy animal at 500 yards+ I have the ability and the confidence to make that shot. Recoil problems are all in the shooters head anyway. No worse then shooting slugs in a shotgun (which I had to use at home before this year). I think half the problem with them is that writers need to grow a pair and quite talking like they will break your sholder
