Really simple. Terrible penetration on straight foward easy shot, then a really funky looking wound channel and angle that didnt match what should have happened.
Now before I get jumped on by guys that like them I will head it off.
~Yes my bow is tuned. I can tune a bow better then most guys as well.
~Yes i had sufficient arrow weight for penetration. 475 grains
~ Yes I admit my sample size was one, however from results it was one too many.
~ Especially consisiderig that with the same set up, with different broadheads this year i killed...moose, caribou, deer and antelope.
