I would have to say that it is a relatively high percentage. Both of the deer that I shot last year were pass throughs and the year prior to that I had one arrow not pass through out of four deer shot.

We are talking arrows not bullets here right?

It would have to be a pretty high %. In the last three years, I would have to say 80-90%. I shot a buck 3 years ago where the arrow high a small branch, and ricoched(sp?) and went thru his back leg. I thought I missed, but he went 20 yards and collapsed. Upon further inspection, I hit a main artery and he bled out. So I guess there are different versions of a "pass thru".
