Brad seems convinced SD rules, I'm skeptical and think other affairs might have an influence also.
If you actually read and comprehended what I wrote, I never said it "rules." It is a big factor with conventional bullets of the same construction.
Again, a 270 Win/150 of same build will out-penetrate a 308 Win/150 of same build. Their velocity is essentially the same (2,800's). This is a fact, and it comes down to SD.
And in regard to the strict example I've stuck to (because this is a thread about the 270 and 308), you're guessing, I'm not.
