That bullet still has 2000 ft/lbs of energy at 200 yards. Stick to 200 yards or less and you should be fine. The story I heard about the invention of the nosler partition is that he shot a moose and had the bullet blow up when it hit the mooses shoulder. He decided to invent a bullet that would keep on trucking even if it hit something solid.
