Thanks Riden. I understand that the 270WSM round travels faster and straighter than the 30-06....what I don't understand is how the bullet performs on impact. The WSM might carry more "energy" to the target at 200m, but what happens when a lighter bullet hits dense muscle and bone? Does it do less damage? Will it shatter a shoulder blade and still penetrate for a good kill shot on a big animal? Or does the extra mass of a 180 30-06 bullet do more damage and sustain energy longer thus a better chance of a clean kill? I'm kind of thinking of the two rounds like a sports bike vs a truck....the bike is going to get there quicker, but when it hits a brick wall it's going to bleed energy faster than the truck would, and do less damage to the wall? Am I wrong?
