Well, probably my worst nightmare concerning hunting has come true. I lost a doe on Tuesday night. I feel terrible, I take full responsibility for what I caused, and I won't be hunting the rest of this season. Had a good broadside shot at 23 yards so all I can attribute this to is myself. I believe that I hit too far back, but still in the ribs. Spent all night Tuesday looking and about 5 hours yesterday. I finally found the arrow yesterday very far uphill from where I originally shot. Arrow appears to only have penetrated about 6 inches and the broadhead shows no sign of encountering bone. I can't fix what happened this year, but what do I do to increase penetration with my set-up? This year I was shooting 47# with a Muzzy 3 blade 75 Gr. tip. I also shoot GT 5575's which I will be changing next year. Please give me some advice and I really hope that this doesn't happen to anyone else!!!
