Any birdshot should only be used as a last resort. Sure it can and has worked in the past, but a 22 has probably killed more people than any other handgun round. That does not mean anyone would say it is the best choice as a fight stopper..
There are too many things that can go wrong with birdshot. You may plan on only shooting at very close range, but after the SHTF anything can happen. What if you are locked in your bedroom waiting for the police and the bad guy is shooting at you through the door. You may have no other choice than to shoot back through the door. Even at close range heavy clothes can slow birdshot enough to keep it from being effective.
If you are worried about overpenetration just remember that buckshot is already designed not to overpenetrate or cause excessive damage downrange if you miss. This is why police use it instead of rifle rounds.
If I ever have to shoot someone in my home I would only do so if I were convinced the intruder is capable of doing more damage to my family than any collateral damage I may cause. I would be more concerned of being prosecuted for having to shoot someone multiple times with birdshot than once with buckshot.
