Replying to the specific scenerios posed is about pointless for me because I don't hunt 30 ft up, and there is no possible way for me to explain in inches regarding a box of where my aim point is. Honestly most times when I shot a deer, I am not even thinking about aiming. I just shoot. Sounds really hap-hazard on paper, but its a process my mind goes thru very quickly and subconciously.

Many of my shots try to pass over the top of the heart when dealing with angles, for both steep in close angles, and deer angled away.The opposite leg aimpont is good for many shots, but themore angle away the more I'drather that exit be inFRONT of theopposite leg based on a buck I shot several years back. 13 yds,18 ft up, angled away. Broke his opposite shoulder...should be deaddeer,quick clean kill. Hardly. It was a single lung/liver that was still alive 2-3+ hours later. Recovered the next morning.

For tight in broadside shots a near lung/heart (or near lung right over the heart) shot is about as deadly as you can get.
