RE: 22-250 for deer hunting
You don't have to get a pass thru on a deer to kill it and recover it. Many traditional set ups do not have the power to get complete pass throughs every time. And smaller people like me don't always get them either because of the reduced draw length and draw weight we shoot.
If you make a good shot on a deer into the lungs it should still leave a blood trail. A lot of the blood coming from the deer comes out of the mouth and nose because it is choking on it's own blood. And I have shot deer with the arrow in them that still left a decent blood trail. I mean the broad head is at least an inch in diameter and the arrow is only between 18 and 24/64's of an inch in diameter. That still leaves plenty of room for blood to poor out of.
I will agree though, a double lung pass through is always better.
