RE: 7mm-08 vs. .270 vs. 30-06
I don't know where you guys are getting your ammo but the .270 and 30-06 should be priced exactly the same assuming the same bullets are purchased. If the store has 30-06 you can rest assured they also have .270 and likely 7mm-08
Fact of the matter is there isn't a pennies worth of difference as far as the dead deer is concerned.
All three are more than up to the task of taking larger than deer sized animals like elk and moose.
The $6 a box of bulk ammo is a moote point IMO becasue unless you are into simply chunking lead down range then you should be practicing with what you are hunting with.
You don't need special ammo to hunt deer with the .270 or the 7mm-08 either. Plane jane power points, or core lokts are excelent deer bullets out of all thee cartridges.
Having said all of this my choice would be the .270 simply because it is the flattest shooting cartridge of all three, will drop any deer species alive, has very mild recoil, and ammo is available any where and every where. The .270 IMHO is the best deer cartridge ever produced and also excels at other animals larger than deer.
Basically get which ever one tickles your fancy.
