    Why would anyone use a 5.56 for home defense they seem significantly worse at clearing rooms than a handgun especially considering it is incredibly unlikely a home invader would ever have body armour on.

    Also obviously this is not the best source in the world but it shows 5.56 going through 9 1/2 walls which is again atrocious for home defense

    “Though the 5.56 bullets showed the most deformation, they were also terribly penetrative (19 panels, or nine walls) and, beyond the first two or three panels, created relatively large holes as they tumbled along their paths.”

      Why would anyone

      People do, for the reasons I said, and others. I don’t agree with it, but it’s a thing.

      shows 5.56 going through 9 1/2 walls

      Because your source says:

      each separated by 3.5 inches

      That’s not going thru 9 1/2 walls, that’s tumbling like 2 feet after initial contact.

      Like, that’s not reflected well in your source, it’s got magtech 10mm (kind of the “hot” production load) barely beating out basic bitch 9mm…

      And 357 less than the 9mm?

      There are very obvious flaws with whatever that guy was doing

        The only reason you listed was its lack of penetration but it seems that it does still over penetrate and the effect of the longer firearm is a major flaw for home defense.

        so if you wanted an actual gun that didn’t over penetrate a handgun with frangible ammo is the much more logical weapon, is it not?

        Compared to drywall the effect of air resistance is negligible so the spacing on the dry wall sheets is essentially irrelevant.

          If it hit one, or hit 100 in 6 inches…

          It would still cause a small fast bullet to lose effectiveness. Because a small bullet is effective because of speed

          I honestly don’t know how to explain it any simpler
