I have only been bow hunting whitetails for 2 seasons (just starting season #3) but after a few badly placed arrows and lost deer I am starting to conclude that deer have been jumping my arrows but it happens so quick I didn't see it. I often feel very good about my shots only to find out I missed the vitals. I can hit the vitals of 3D targets consistently. Also watching the slo-mo videos on hunting shows of the actual shot I notice that most deer almost always manage to crouch down a few inches before the arrow reaches them.
I've heard that bucks especially big ones tend to jump the arrow less often. I hit my last deer exactly where I was aiming and it was a 2 1/2 - 3 1/2 year old buck who was fixated on two does at the time during the rut so maybe he didn't jump at all, I don't know.
So here's my question: Do most bow hunters aim low to account for the deer crouching down to run after hearing the bow? If so where do you aim? Is there a distance so short that the deer doesn't have time to move or so far that they don't hear the bow? My bow is older (2003 Browning Lightening) 62 lbs and not as fast or quiet as the new ones.
