Home Forums Hunting & Shooting AR and Tactical Rifles What AR ammo for indoor home defense? (223/5.56)

Thanks, Tex. The M193 expending most of it's energy in 10" of gel looks like the best for home defense out of all of those. I'd like to see M193 compared to SP or HP 223. I'm looking for something to stop a BG without injuring neighbors. Don't see a need to shoot through barriers in my own home.
