Bird shot at close range is a killer, you can get their attention with both Buck & Bird shot! 
Actually, bird shot at any range beyond point blank isn't a killer, particularly .410 coming out of a three inch barrel. As far as getting their attention, if I have to shoot somebody, I've already got it, and not in a good way. If you must own one of these toys, at least load it with the .45 colt (Haz would proud of me

) Otherwise you're just begging for pain.
