About this time last year I whacked my best hog to date on public land (see 5-25-09 thread titled "DIY Public Land Success"). I recently started scouting again, and had them patterned pretty good. Last weekend I went back to try my luck, and sure enough, I got a shot off. But, here's the details: 25 yard shot (new Z7 bow), slightly downhill. Four hogs in the group, the one I hit squealed loudly (the rest remained silent) and they all bolted. I drilled this pig. I waited a bit, went to the kill site and no blood! Not even a drop. Also, no arrow! All my recent kills have been pass-thru's - because of the angle of the shot, finding my arrow should have been easy. I looked for an hour before it got dark, went back the next morning and looked for four hours! No blood, no arrow, no nothing! I'm kind of sick about it. The only thing I can think of, is that I made a less-than-perfect shot - maybe stuck it in the ham (no blood) and the arrow stopped at the opposite hip bone (no arrow). Hate the thought of a wounded animal, maybe I can learn something here so this never happens again. Any help would be appreciated. Thanks!
