On my kill this year, the tip (which are prick-your-finger sharp) just caught the back edge and splintered the back part of the rib, then the blade came by and cut it almost in two...but at the same time changed where the arrow was heading.
That my friend is a mix of poor spine, low FOC and thin blade heads.
Which is the exact same reason I wont use a head that is under .040 thick.
I shoot lighter 100 grain field tips sinceI do quite afew 3-D tournys.
I use 175gr screw in points for 3d
Straightarrow? Ausie? Would one of y'all like to take this one? I'm tired of arguing with this guy.
