I would have to say stepping forward,as the shots i have made, that were back of where i wanted to hit were caused by two mistakes i made, not leading the deer and or not stopping the deer, sometimes caught up in the excitement, we react to quickly! just my .02$ worth! i don't have the bow kills that most have on here or the experience,but I have kept logs of every hunt for 36 years and after looking thru them the past couple days since curt started this thread i have viewed a patteren here for me! thanks curt!!I'm sure this is not where your going with this thread but I like that it got me thinking! I've only lost one deer to a to far back hit, this was when i first started out as a kid, my first trad hunt ever, bear 4 blade head, shot while the deer was moving,no leading, I looked for that deer for seven months,and finially found her in the spring after snow melt!I learned alot from that one deer,she went 150yards,and i walked past her 100s of times in that seven months!!
