Here are a couple photos and summaries;
First is a before & after photo of a 45/70 bullet recovered from a 9-pt buck this year.
Bullet entered the neck just rear and below the left jaw-bone and ended under the skin in the white-hair next to the anus, (fell out while field dressing.) Estimated penetration was 56-inches. Bullet left the 26" barrel at around 1600-fps [its one of our "pet loads"] and the deer was 82-steps distant. Deer dropped upon the shot. We never thought we'd recover one of these from a deer but...

Next is a photo of a 45 Colt load made specifically for deer hunting with the 454 Puma rifle made by Rossi and sold by Legacy International.
It is a 230gr Gold Dot with all the IMR4198 we could get behind it at a O.A.L. of 1.796"
for velocities right at 1400-fps from the 20" barrel, (the load gives about 925-fps from a revolver.)
This bullet was recovered from a doe that was uphill and about 45 steps distant.
The bullet struck low and rear of the ribcage, entering the stomach going forward, upward and across the body to exit just above the point of the shoulder. The bullet was "dangling" in the flesh and gut that was protruding from the wound which was about one-inch in diameter. The deer was knocked to the ground and nearly rolled uphill from the impact of this hit. It died on the spot.
We never guessed a 230gr Gold Dot would go this deep in a deer, about 16 to 18 inches (we think.)

Another view of the 230gr Gold Dot loaded and recovered:

Hope these images come through.
We need to start taking measuring tapes to the field with us.
