It's certainly going to get thru any clothing worn & even from a riot choke, those heavier pellets will certainly pentrate heavy muscle & bone. The only reason to choose birdshot is becasue it's all you have.
Choke means nothing at 7 yds. I load turkey loads because they are higher quality shells (high brass, more reliable feeding/ extraction) than most target loads. Buck shot will penetrate walls/ floors etc more effectively than bird shot. A real issue in my house. Once bird shot loads have passed through sheet rock, doors, floors etc they may still be dangerous, but much less lethal than buckshot.
At 21 feet a skeet load will render a canadian goose into mangled sack of goo, so I have no idea what you are talking about with regard to larger birds.
