I was refering to the 30-06 in perticular. The 7mm mag shoots flatter and has more energy then the .270 even with similar weight bullets.
Here Federals ballistic catalog. After you download it you can compare all sorts of loads and it will show you a graph.

That didn't tell me at all. It lists only Federal cartridges, and for the .270 Win lists only 130gr. The Federal 130gr is sloooow. Not a good choice.
Here's some interesting real world data; worth reading all of it:

"By going to a big magnum cartridge, and suffering the added recoil, muzzle blast, and expense that entails we have only gained an average of about 20 yards (6.6%) in MPBR over the standard .270 Winchester."
