As stated by Bravo 4
You already have the 06, so use it!

Accuracy has alot to do with barrels, action squareness yes. But it doesnt stop there. Case design is involved as well. Long skinny cases are less efficient and more finicky than short stocky ones. The 30-06 is conciderably longer than the 308 in porportion to its diameter. It isnt nil.
Anybody who claims a 308 isnt any more accurate inherently than the 06 has never spend much time using both side by side.
"The less powder a cartridge uses the easier it is to get each shot (velocity) the same as the last, but the difference between the 308 and 30-06 is virtualy nil. "
I still stand by that statement. The the variation in velocity from shot to shot or ease/difficulty of finding a consistant load between the two is virtualy nil.
As to the newly adopted 308 breaking all the 06 records. Well that wasn't necessarliy because of the 308s "inherent" accuracy. It is now known that the weapons used in comparison were not built to the same standard. The 06's were built and chambered to older "looser" specs, and the 308's were built to much tighter tolerances. Not only that but the weapons used to compare the two were not the same in quality or age. The 308's were newly manufactured while the 06s were vintage battle weapons that had seen action.
So why then is it so surprising the 308 came out on top. Well it's not!
Now as i said before, if both weapons are built to the same spec with identical neck and throat dimentions, useing identical components, the only difference would be velocity. I still stand by that assertion.
Now, I may very well be wrong in that assertion, but I don't think I am. Again, that's a personal opinion!
To say that one is more Inherently accurate is to say that a 308 would always be more accurate than a 06, which I think any reasonable person would agreed that that's just not true.
There is where I leave my opinions.
Now, the reason the military was so eager to adopt the 308 lies more in the fact that they found a lighter more compact cartridge that could utilize a lighter more compact weapon with less recoil and @ modern pressures there was only a slight decrease in velocity. The 308 was replaced by the 223 (a 400m weapon), not because the 223 was inherently more accurate, but because the design parameter of the 7.62 being an 800m weapon was found to be more than what most shots in battle would be. The 06 was origionaly design to be an 1100yd (approx 1000m) weapon, then it to fell victom to changes to the required range in battle being shortened to 800m. Why carry an 1000m weapon when you only need and 800m weapon, then why carry an 800m weapon when you really only need a 400m weapon.
Not only that, but the military desired a smaller lighter cartridge to maximize the number of rounds that a soldier could carry.
