I just shot a doe last week with a 100 gn montec. 330 Gps from my xbow. No blood trail. Nothing. She only went 50 yards luckly. I DON'T LIKE NO THAT THERE WAS NO BLOOD TRAIL.
The lack of a good blood trail is not always the fault of the broadhead. A slightly high hit with a higher than optimal exit wound will result in the chest cavity filling with blood but a poor blood trail. Not bashing you, just speaking from experience. Been there myself more than once.
