How do theses rounds compare to each other? I heard that they are all great calibers with a long history. How is accurate are they at 250, 500, 750, and 1000 yards? What about price? How versatile are the rounds? I heard the 30-06 has sabot rounds for smaller critters like coyotes, but also larger rounds for things like elk. What twist rate is best for them?
good best better in that order respectively
They all have their "thing". The 308 is better for autoloading rifles due to it's shorter length and is considered the accuracy champ. The 30-06 is the most versitile and the most powerful of the three. The .270 is a the flattest shooter, being created for "western" hunting where shots were likely to be out there.

How accurate are you at 1000 yards?
I am sitting in my angry chair!
I have found the 308 the most inherently accurate of the 3, however IMO when talking over 200yd the shooter makes more of a difference then what you'd see in those cartridges. If forced to say I'd say the 270 has the best chance at better groups at a longer ranges due to flatter trajectory. The 30-06 IMO only shows it's advantage over the 308 if you're shooting bullets over 180gr.
Blobman likes 30-06.
O.S.O.K. it is for a bolt gun by the way.
Aliceinchains, good point.
mriddick, so the 30-06 can match the other two with the right round.
For the shooting I do I see don't much difference in the 3, I normally don't shoot over 300yds so I go for the one I find the most accurate with the least amount of work (for me the 308). For long range shooting I'd rank them 270, 30-06 and 308 due to case capacity and ability to shoot lighter weight bullets.Originally Posted by Focused Gunfire
BTW I know there are sabot loads for 30-06 and 308 but I've never found them very accurate.
No right twist for a caliber, its matching twist rate for bullet length. Same for distance, no perfect caliber but each has a bullet that is optimum for distance shooting.
It can be argued that the 30-06 has the most versatility but there isn't much it can do that the .308 can't match but with less recoil and in a shorter action.
270 will take anything from moose to antelope depending on where you live. Shoot them all and see which one makes you giggle the most.
I am a .308 man by choice and have shot it in competition at 1000 yards. That makes it right for me but maybe not for you. If I was going someplace where the critters were large hairy with sharp claws and big teeth I would happily trade it in for a 30-06 with 200 gr bullets.

308 as well, 1 does most. Thats how I see it.
Crap. They are virtually the same damn thing!
Trying to get on the no fly list, one post at a time.
I thought the difference would have been based on rifling?
The '06 has more case capacity than a 308.

Ballistic coefficient is what I was referring to in a clumsy way.
So what would be the difference in the ballistic coefficient of an 06 and a 308?
Just curious..
More choices for factory loaded .308- especially in terms of match rounds. Plus you may be able to shoot mil surplus 7.62 X 51 nato for cheap trigger pulls if you want. That's why I went with .308.
Plus you can use a short action bolt rifle if you choose- but be aware if you go that route you can only re-barrel it to another short action round.
If you go with a long-action .308 you could easily re-barrel to 30.06 or .270 win later...
In looking at the cases with long range shooting being most important 270 and 30 cal would be BC, 308 VS 270 and 30-06 would be case capacity. I'd rate 270 and 30-06 over the 308 based on case capacity, then I'd rate the 270 over the 30-06 based on BC, my personal choice although would still be 308 (although as noted I rarely shoot over 300yds any more).

I don't have a .270, but I reload for a .308 (M14) and a .30-06 (M1 Garand).
The .308 wins in using less powder for reloading. I think my usual target load is 41.5 gr IMR 4895 in .308 whereas I'll use around 49 gr IMR 4895 in 30.06.
Both use the same bullets as opposed to the .270
The .270 is based on the same case as the .30-06 necked down.
I think the .308 is more efficient in design. You get virtually the same performance in a smaller package.
I prefer short action cartridges as I use semi-auto almost exclusively and in the case of my Mdl 99e the shorter round is better for its lever action. Mine is .300 Savage, but this rifle is also found in .308.

Sierra Matchking .308/178 gr BTHP/ BC=.496
Sierra Matchking .277 (.270 win)/135 gr BTHP/ BC= .482
Sierra Matchking .308 (30.06)/180 gr BTHP/ BC=.494
If one wants a game changer then the next step up is .300 winmag:
Sierra Matchking .308 (.300 winmag)/ 220 gr BTHP/ BC=.624
But I digress...
Now you have it correct; the BC is the same and the 06's case is longer.
.270 win is the best of the bunch IMHO I have owned and shot all three...
BTW ..no they are not all the same DUH......
