I think it depends on the discipline, NSRA .22 in the post uses the outermost edge, but ISSF (Olympic rifle/pistol, for example) uses the innermost edge.

Isn't .22 a bit small for deer? I don't know anything though, so this isn't an informed objection just a question. Or were you just learning fundamentals of shooting before trying a bigger caliber?
