Have you fired a short barreled 12 gauge in a small room without ear protection? Pretty devastating ... on both ends. Or maybe you can offer the intruder a coffee while you dig out the earplugs.I've thought about using TSS T shot for home defense, but I haven't patterned them. T shot gives 24 pellets per ounce and I'd consider that better odds than 9 or 10 pellets of 00BUCK. If you step down to #2's you get 54 pellets per ounce, meaning 108 for the loads you are looking at!
Three pellets of 00 buck in the torso = a pile of hamburger. Tungsten T shot would probably pass through an intruder like he was butter ... even if he was big as Bubba Smith. Then through several rooms in the home ... and maybe through the home next door. Sometimes there is such thing as too much gun.
