Just for giggles.....

1) from 15yds away and 30ft up, deer broadside -- you're awfully high in the tree.....so you're gonna have to hit high on the deer. I'd AIM FOR THE EXIT HOLE to be just behind the off-side leg and (naturally) low.

2) 15yds away, 30ft up, quartering away at a 45 degree angle (meaning moderately quartered away) -- 45 degrees quartering away is not "moderate". It's pretty severe....and VERY severe from that angle (the angel of the shot.....not the deer). You're gonna need to AIM FOR THE EXIT HOLE to be in front of the off-side leg and (naturally) low.

3)20yds away, 30ft up, quartering away at a 65 degree angle (meaning severely quartered away) -- Previously answered.

4) 8yds away, 20ft up, broadside -- See No. 1

5) 8yds away, 20ft up, quartering away at a 45 degree angle See No. 3
