Please don't take this as criticism... it's not. The amount of blood left on the ground is primarily influenced by 3 factors:
1) shot placement
2) pass through penetration
3) the level of BHD sharpness
Since you made a good double lung shot
, and achieved a full pass through
, that only leaves one of the major variables in question...
I'm not trying to sell sharpeners. I don't care how hunters go about getting their BHDs sharp but the difference in bloodtrails from a pretty sharp BHD vs. a just crazy sharp head will almost always be night and day regardless of the BHD size, blade count or bevel configuration. Very few things in bowhunting are set in stone but in my experience, this comes very close.
Excellent shot. Congratulations on the buck and especially the recovery.
