Let me guess, inside 100 yards and your MV at the POI was above 3150 fps?I shot a buck chasing a doe on an opposite ridge a number of years ago, he went down in a heap. Turned my attention to the doe, shot her, she dropped as well. Looked over to where the buck had laid and he was gone. Crossed the hollow and found a 50cent sized spot of blood but nothing leading away from it. Circled around for half an hour and couldn't find a drop. Gutted the doe, went back to camp got my buddies and we searched for several hours without finding a sign. A week later a guy on our lease drug the buck in, he had shot it chasing another doe. It had a fist size chunk blown out of his back which had scabbed over, it was amazing the deer could even stand up. The bullet had went between his lungs and spine. Was shooting a 25-06 with 117 gr Nosler partition bullets, 52 gr of 4350. A rifle and load that had killed a bunch of deer for me with no issues.
