i know both are very good calibers i have heard people say .308 and 30-06 just wondering

Both are VERY GOOD calibers !

Both are great! I just prefer the .308 Winchester.

On whitetail deer, there is no real difference as far as I am concerned. However if you hunt larger animals like elk or bear, and use 180 grain or larger bullets, the 30-06 starts to have a bit of an advantage. In the .308, I think that the long 180 grain bullets start impeding on case capacity so you start giving up velocity due to reduced powder charge. I myself choose the .308 since I live in the southeast and don't hunt elk or bear. The 30-06 produces about 100 to 200 fps more than the .308 in most loads. The .300 Winchester magnum produces about 100 to 200 fps more than the 30-06 to put that in reference.

Maybe an tiny edge to the 30-06 due to the large range of different loads available for it.

The best one is the one in your hand when the you see a deer.

Only difference is long or short action.

Recooil is another factor to consider, depending on the amount of shooting you do.

There are many "good" Cal. out there, but good for what? as in what are you planing on doing with it?
FYI Both are related, closely. The .308 was the product of a Gov. contract to develop a more efficient version of the 30-06. It shoots the same bullets at the same velocities. It is a more efficient use of resources than the .30-06. It needs less brass and less powder to do the same job. That was enough for the Mil. to jump in with both feet but it's apparently not been enough for the sporting world.
In the hunting world the .308 holds no real advancement over the .30-06. Reason being that the same reasons why the Mil. wanted it just don't transfer over to the sporting world.
It is worse because of 2 major reasons.
#1 its new and so its more expensive.
#2 It is less popular than other rounds which get the job done just fine right now. Which makes it more expensive.

P.S. Seeing as .30-06 is the cheapest deer cal. out there I decided to get a gun in that for killin them deer. It just makes sense.

I have shot both and hunted with both. They are really quite similar, with the overall edge for "all game" probably tipping in the 06 favor. However, I like the .308 in recoil, shortness of cartridge (especially in a bolt), and accuracy. I have a .308 and have rid myself of the 06 though it is a good caliber.
