That really is pretty normal for a 50 cal. heavy lead conical. And normally the expansion occurs below the nose of the bullet through 1st and 2nd band of the bullet.
At that point the meplat has become so wide that it really slows the velocity and energy of the bullet - but normally by that time the bullet has done its work.
The really GREAT thing in my mind is that those large lead conicals do not 'PANCAKE' or blow up like the lighter lead conicals.
