First 30-06' is a fine all around cartridge for most anything in North America,if you're looking for a bit more power the 7mm rem mag is a nice choice.There are also a lot of other cartridges that will do long range and deer hunting with less recoil than your two choices,for example 7mm-08 or 260 rem.among other choices on the market.
I chose the 7mm rem mag nearly 25 years ago and have been happy with my decision for me and its application. I originally wanted the 300 win. for future elk hunts when I came across a near new Remington 700 Bdl 7mm rem mag. w/Leupold VXII 4-12x40 in a pawn shop,bought that rifle in July at a really good price. I have never regretted purchasing the 7mm rem mag for elk/deer and for just a hunting rifle the 7mm rem mag has excellent long range accuracy.
