Note I said “LESS walls” than 9mm…a 5.56 will still go through walls, plural.Hmmm okay. Wouldn’t a speedy 50ish grain bullet still pass thru windows or walls more or less intact (avoiding studs) & be a keyholing, tumbling threat even so? Don’t know so hence the questions
But the light bullets fragment, yaw, and shed velocity quickly, where the 9mm is basically turned into a RN bullet when the drywall plugs the cavity with no to minimal expansion.
If I was running a 5.56 as a HD long gun…I’d be running 45-55gr varmint loads such as a VMax or a Nosler Ballistic Tip.
