The ulitmate deer bullet is the one that shoots the best and has the characteristic for your situation or needs. Litterally a ton of bullets and reason why you would or could use them for deer.

I use Ballistic tips because of long distance shot opps, accuracy and expansion. I might add I also aim for the lungs so what bone contact I get it is either rib(minimal) or opposite shoulder. If I were hunting strictly short distance I doubt the BT would be my first choice, although I have taken animals inside of 50 yards with it the Blood shot and expansion was a bit to violent for me to consider it as the best bullet for this situation. I would choose a bullet of stronger construction like a Nosler Partition, Bonded, etc. Same can be said if I was wheel shooter (shoulder or breakdown was what I wanted to accomplish).

Like I said match bullets to your situation and desired outcome then shoot them to find which one stands out in accuracy. For most hunters that is the desicion maker which one groups the best b'c it give them coinfidence in making a good shot and they have already decided it is a good choice for their hunting needs.
