Same here RT. 20 gauge double Ithica circa 1920 with 3 buck.
Ditto on 20 ga for close in security and indoors. Packs a good wallop close iup but does not penarate walls nearly as much as any single bullet round, including a 22lr. I would not even consider a 22lr for home defense either. Perhaps a 22 WMR revolver for an experienced shooter but nothing less.
