I agree, the past two seasons I was getting pass throughs I shot three deer and all of them died within sight. Now this season, I've hunted with my brother where he has shot two deer no pass throughs and I have shot one and did not get a pass through. It leads me to ask; what are the mechanics of a pass through everytime. The only thing that has changed in my set-up is my arrows, broadheads are the same and I sharpened them. Does the weight of the arrow make difference? I'm shooting a little lighter this year.
