Well drywall isn't AR500 steel, and it's still going to go through a few walls easily enough. But the 5.56/.223 sheds energy faster, deviates from the straight line path easier, tumbles sooner, and loses energy more quickly. Here's an article which collects a bunch of other articles for us:Yeah, that kinda makes sense, if you were using 55 gr I suppose it could go that way. The old tumbling 5.56 story has been around since the 60s. But based on real-world use, I have seen them go in one side and out the other. We are even allowed to use .223 on deer up here, just not FMJs. You are also assuming people are using 55 r projectiles, or at least basing your response on that.
I'm not trying to argue with you, just I don't like to see random "expert" from the interwebs word taken as gospel
Oh, I do not doubt that, I have seen what a small limb can do to a .308 while deer hunting and 5.56s deflect off windshields. Bullets do funny things sometimes.I've seen several tests which stack drywall boards one right after the other in a series with only inches between them. I think the better test, which I saw on Tom Gresham's video channel (somewhere), was when they built walls and set them out at typical room distances of 10 or more feet apart then did the tests. It was interesting to see the flight path deviate significantly, sometimes by yards (ims), and to see the fragments hit the wallboards instead of complete bullets
