Try to imagine the flight of the arrow as it passes thru the deer, you want to hit as much of the vitals as possible. The lungs are the biggest vital and with a double lungs shot the deer should be recovered in a distance less than 100yds. With that said your aim point will be determined by the angle of the shot. If you are in a tree stand you may have to hit a little high and imagnine the exit hole so it hits the vitals as it passes thru. On quarter away shots you may have to aim farther back so it passes thru and takes out the both lungs. If you have a 3D target set it up for 1/4ing away shots and practice and visualize the arrows path thru the deer. On a deer that is broadside put your pin on the front leg follow up the leg to where the leg & the shoulder meets then move the pin back approx 4" towards the center of the deer. Don't shoot until the deer has the leg that is facing you forward. When the leg is forward it opens up the lungs & heart, you won't hit the shoulder plate. Then again if you want take the double lung shot if broadside that works and is less of a chance for a bad shot.. Wow that was a mouth full, sorry for the long winded reply.
