I posted this on another site December of last year. It is my experience with the 3 blade bloodrunner. Sorry for the mention of KE but it is what most are familiar with. A mention of momentum would not be a reference most know.
A week ago I got a chance to see how the Bloodrunners perform on a deer. Of course they are razor sharp right out of the pack and "fly like fieldpoints"

but I wanted to see how they did on a deer.
The deer was quartering away at about 8-10 yds. The arrow went through the near side backstrap and came out into the far side leg about half way between elbow and shoulder, breaking it in two. Deer went about 30-40 yds, hit the ground, coughed up about a pint+ of blood, expired. It would have easily been a pass through except for the bone hit.
The bow is an Allegiance @ 54lbs, 29" DL, smooth mods. The arrow is a CT Whitetail XP, .400 spine with a 50 grain insert for a 17% FOC, weight about 400 gr and speed around 260fps with a KE of 60 ftlbs.
The Bloodrunner busted the bone clean in two with some smaller pieces and
no noticeable damage to the BH. I will be using these some more in the future. This particular BH is still good enough to kill deer but it is now a fox BH.
