Good question. Some claim one complete rotation, but I don't buy that. I know for a fact, that a snubnose will never be as accurate as a 6" barrel for 44mag.
So for a 308, with 1 in 12 barrel, I don't think you would want anything shorter than 12". Surprised, i have never read an article on it. I have read alot of articles on what is the dimenishing returns for velocity.
