For jumping up elk in dark timber, where one may have to drive a bullet on a hard angle ( or even up the keister!) what weight and bullet make, and how fast would break a lot of bone, penetrate? I can only "assume" what it would take as all three cow elk I've taken have been broadside and all were in fairly open to wide open. This in itself is kind of rare in the timber. I'd like your opinions, especially you Northern moose, bear, big Northern deer hunters!
