For the newER guys out there.....that spot "behind the shoulder" is misleading (IMO). The angle of the archerto the deer (both vertically and horizontally....in the case of a quartering shot) should dictate arrow path......and the path of the arrow through the vitals should dictate entrance point in EVERY scenario.
Simply stating that we aim "behind the shoulder" can be VERY misleading to the novice archer who hasn't taken into account a deer's anatomy.
Just my .04......(.02 and .02, amended)
