Is a 7mm mag the gun to get or is the 30-06 or .270 a better choice?
What do you plan on hunting? Any of these will kill a deer easily within 300 yards without any guesswork. The .270 is a little more accurate than the 30-06 past 300 yds. But the 30-06 has a little more energy than the .270 especially past 300yds. The 7mm is more accurate (if you don’t flinch when you shoot it) and has more energy at greater distances. It has more recoil. If recoil is a problem the 30-06 would be my first choice over the 7mm. If you hunt bear, moose, anything larger than a deer the 30-06 would be better than the .270.
