I had the same result of spare blood twice this year shooting 140 gr Fed premium nosler BTs in 7mm08. Both bucks dead as Roy Clark 30 yards away. Both shot from an elevated position just behind the shoulder and exiting the other side slightly into the lower rear of shoulder. Not much blood for the first 20 yards but pretty good blood the last 5 to 10 yards to where they hit the ground. I could see where both piled up as it was in an uncharacteristically clear area. Just for kicks I tracked backwards to see how much blood was from where they were shot to where they stopped.
I was surprised at the lack of blood.
