RE: you will not believe this
that's definitely possible.
Two years ago, I shot a buck in Preston County, WV and also hit a doe behind it with a .300 Weatherby Mag. I didn't realize until I was dragging him out and ran across a second blood trail.
I was suspicious, so I backtracked and found that the trail began right where I fired. There was some hair in the snow as well.
I tracked her for about an hour, and she never stopped. If I had to guess, I think I lodged it in her left rear quarter. I hit a lot of bony mass in the buck, so it probably lost most of its Kinetic Energy before impact.
It would've been worse had I not hit the buck's shoulderblades.
The doe was standing about 8-10 ft. behind - I didn't even see her, b/c I was focused on hitting the buck.
