I've only taken one bull moose so I'm no expert on the subject. But I hunted with a Savage levergun in .308 shooting 180 grain core-lokt ammo. Distance was about 125 yards. Two quick shots into the chest organs toppled the beast. We found both bullets curled up like the magazine photos. Damage to the lungs was quite ghastly.
