I have seen first hand a few of the horror stories I hear about ballistic tips at close range from the 7Mag. Like hitting a rib and having the bullet exiy the hind quarter on the same side. This was several years ago.
I always find these type of stories amazing since I have killed around 40 head of big game with ballistic tips at muzzle velocities from 3340fps to over 3500fps and have never witnessed any similar events.
