Doesn't it also refer to firing continuous rounds with a single held-down trigger? Semi-auto would be a round per squeeze without the need to re-cock after each shot, and burst-auto would be multiple rounds per squeeze (usually 3, IIRC), right? So, a shotgun, which fires one shell full of multiple pellets, is still not auto (semi or otherwise). It might be single or double action, though, but that's different...IIRC...sorry...just babbling again...
