RE: Rage and blood trails.....
I have taken 4 deer this year with the 2 blade. One buck, 3 does. All had amazing blood trails. My buddy took 6 this year, all with Rage 2 blade......same results, massive blood trails. I would also guess it to be shot placement rather than the BH as far the lack of bloodtrails you are describing. Did you hit the buck high in the lungs?
