308 & 30-06 ballistic differences.
 
I don't want another caliber debate, but which is accurate further out? What are the other ballistic differences?

The 30/06 will shoot a little farther since the case can hold more powder shooting the same bullet.
Ballistics are close out to 600 yards,and then the 06 takes charge.
Depending on the barrel twist,the 30/06 can shoot heavier bullets than some 308's.
The 308 wins all day in the recoil dept,a lite weight 30/06 will let you know it's there after a few shots.

Hillbilly is pretty much spot on. the 30-06 has just a little more muzzle velocity than the 308, but it's not a huge difference, usually about 100-150 fps difference when using the same bullet weights.

now for a hunter, when hunting game that would require larger weight bullets like 180-220 grs. the 30-06 due to it's longer case has a little more advantage.

and yes the recoil isa bit gentler with the 308! personally i enjoy both and own both, but if i were to have to make a choice and only have one of them, it would be a very hard choice and i do believe in most cases i would choose to go with the 30-06. IMO, it has just a little more versatility, not a huge amount, but a little. the 30-06 would allow you to stretch your distances just a little further.

^^^^^^^

As far as a hunting rifle goes, I will always choose 30-06 over 308. I do prefer the 308 in my 'tactical' rifles though because of the case length.

They are identical until you start in with bullets over 168 grains. At 168 is the point where the case volume of the 308 pretty much ends its usefulness.

So there is no benefit to using a 180 grain over a 168 grain .308?

Rate of twist for .308 is right for bullets about 168 or less. A 180 will not stabilize as well.

I use a 30/06AI and 165gn Game Kings and to date everything it has touched hasn't come out of the meeting real well.
I've dropped feral cats, goats, pigs, feral dogs ,feral horses and donkeys out to 150yds plus and deer.
The 30/06 will handle projectiles up to 220gn which here in Australia will handle a Buffalo but it's still a tad on the light side but things like camels and scrub bulls can be handled fairly well by this calibre.

The .308 has it's place and along with the .270 are all very close in performance until you start using 165gn plus projectiles in the 30/06 and that's where the 30/06 starts to shine.

Own, reload, shoot, and hunt with both, if you want a super light compact rifle the 308 does 90% of what the 06 does in a smaller lighter package.
If you prefer a full sized Sporter rifle the 06 is aprox 100fps faster across the board and even faster with handloads. Never run into pressure issues working up my 06 but I often do with my 308.
Both are more then enough for deer hunting but going after bigger game the 06 has a clear edge.
I love both and have no intention of getting rid of either any time soon.

there can be in the type of game hunting you are doing. If you are going after thick skinned, heavy boned annimals like Caribou, Elk, Moose, Bears, etc. or hunting in thick brush, the heavier bullet may be what you need to get the penetration on those big animals or resist deflection by twigs.

If you have to use a 180 or 220 grain bullet, the .30-06 is your Huckleberry between the two calibers.

Up to 168 grains, both rounds are pretty close other than the extra velocity you can wring out of the '06. Once you get to 180 or bigger rounds, the .308loses velocity pretty fast, because to try to stay in the sme velocity range, the pressures, get to high, too fast and you run out of capacity in the case for the extra powder to fuel that velocity.
