Why .223? There's much better alternatives out there, and not very expensive either.
No. There are not. Other options usually overpenetrate except with very expensive premium rounds, are less effective, or have prohibitive blast and recoil. Frequently other defensive options have more than one of these liabilities.
The only really good reason to use a shotgun for SD- loaded with good ammunition like a traditional Foster slug or #1 buckshot- would be if the resident already owns a shotgun, but not a carbine, or shoots a lot of shotgun sports, and so already shoots the shotgun at a very high level. Almost all handgun rounds are less effective than .223 at quick incapacitation unless your home defense is against large dangerous game.
