It's not so much a particular cartridge that is accurate or not accurate, it's the rifle.
The reason there are so many Ruger upgrades is because they're necessary.
Besides, didn't you post previously that the 30-06 is "very accurate"
Do you believe that if a person were to go out and buy two rifles, one in 308 and one in 30-06, but otherwise identical, that the 308 would be the more accurate rifle the majority of the time?
