That may work for a nice broadside shot from ground level, but what will that do for a quartering away shot.
Trun the 3-d target on a 45 degree going away, coming toward. This is the beauty of a 3-d. Set it up a million ways and shoot all of them. Sometimes I like to set it up in a shooting lane and try to thread the needle. I practice shots on my 3-d that I'd never take on a deer and this give me the experience and confidence to drive home the shots I do take.
