Not going to bash you but I'm not going to do it myself. I would just use a heart/lung shot and have an excuse to shoot an extra deer every year if I wanted to make up for lost meat. If your going to practice a bunch and get really good with a particular rifle for headshots, why not use that learned skill to punch a clean hole through the ribs with a semi-explosive .223 and turn the lungs to mush with minimal damage to the far side ribs?
