We had two cow elk drop to the shot this season with shots low to mid chest placement. No cns damage I could see or damage to the heart. Classic lung shots. Both were close high velocity impacts that made the lungs soup. One match bullet, one not. I think every shot and animal are different and some do drop without obvious cns damage. Also had a match bullet impact with similar fps and placement run off a bit last season. So I dunno.I have the distance ran in the poll.
Technically, immediately dropping at the shot, I think, has a CNS component, so I didn’t include it.
