That little doe was hit with a 185gr 40cal at around 120-140 yard IIRC
Couple years ago i was sitting in a blind in deer gun season. The .50 Encore was loaded with a 250 grain Shockwave bullet. Luckily, i also had a Remington 700 in .308 in the blind.
Big doe showed up about 80 yards in front. Shot the animal with Encore. Doe lay still 30-45 seconds then jumped up. i shot her with the .308 and she went down to stay.
The muzzleloader bullet hit the deer about where yours hit. Bullet did not expand and the wound was much smaller. But it did ruin some meat.
