My admittedly somewhat limited experience is that animals of any variety are not long for this world if they have holes of any size in their lungs. If the bullet passed through the vitals, then the deer is there somewhere. I hope you're able to find him.
I'm going deer hunting all next week and I'll be using a .243 that has already dropped one good sized buck. I'm using 95 gr. Fusion factory ammo this year.
