For me 40 yrds is max, and only under perfect conditions. At that distance I really think about it. I have made killing shots at that distance, and I have passed on 40 yrd broadside and quartering away shots because of wind, uncertainty of clear arrow path, and deer behavior.

Oh I am very good on the practice range at 40, but to shoot at a live animal is much different. Ive learned from experience that alot can go wrong from the time of release to the point of impact, even at 10 to 15 yrds.

I feel horrible when things go wrong and a wounded animal is the result. Hey, this is hunting and things do go wrong. Even the surest of shots dont always end up that way. If I make a shot within my comfort zone and something goes wrong I feel very bad, but I can go on to hunt again. I would have to do some real soul searching if I wounded an animal on a marginal shot that was made outside of my comfort zone. Over 30 yrs of hunting and over 50 deer taken and I have only wounded one deer.

KE has never entered my mind when drawing on an animal, the kill zone and my comfort zone are all that matter at full draw.
