This is just my opinion for what it is worth. Do not buy the 270. There isn' t enough difference between 30-06 & 270 to really matter. Also, the 30-06 is more versatile. For instance, you can shoot factory 150 gr. loads for deer and they are nearly as flat shooting as the 270 130 gr loads that are popular. The best thing about a 30-06 is that you can go up in bullet weight all the way to 220 gr. in factory ammo. Also with the new Federal High Energy loads and the Hornady Light Magnum loads available your 30-06 is very close to standard 300 Win. Mag. velocities. Shooting the HE and Light magnum loads will be harder on the shoulder than the standard factory ammo. I do have a 30-06 w/Leupold 3.5X10X50 on it. I use Federal HE loads with a 180 gr. Nosler Partition to hunt Elk in Wyoming. This load groups under an inch all day long. The listed velocity is 2880 fps. Over my chrony I get 2862 fps. This is only 98 fps slower than standard 180 gr loads for the 300 Win. Mag. I hope this helps you.

If you just want a new deer gun look to the 7mm-08 or 260 Rem. I own both. Low recoil, enough power, and flat enough trajectory for deer out to 250 yards and a little further if you are a good rifleman.
