Your buckshot comment reminded me of what one gun dealer told me: Use birdshot.
Buckshot tells a capable defense attorney that you’re itching for a confrontation. Birdshot still kills, but kills the argument over your Rambo wishes.
FYI, nothing more.
B.S. I say. If someone meets me in my hallway at 3 a.m. I am not worrying about my defense strategy of birdshot vs. #4. Better to be judged than carried as they say.
Plus, #8 birdshot just might piss him off. See this interesting test below,of various shoot X .12 and .20 gauge guns. '00' and '04' is they way to go for home defense.
