It will penetrate many walls. Check the box o' truth.foshizzle said:For home defense I would pick the .223. Less likely to punch through things. Like walls.
someone is going to have the explain the physics to me on that one...slabertooch said:I remember from my training that it wasn't uncommon for a 5.56 round to go into the body and exit from an unusual location. Drill Instructor told me of a buddy who caught a 5.56 in training, entered through his lower abdomen and exited up out of his collar.
simply, a unstable round enters the body cavity and tumbles, then stikes a bone or other hard surface, yes it will deform, but because of lightweight and high speed, will actually bounce inside the body cavity, actually more like skip.glockgirl said:someone is going to have the explain the physics to me on that one...
hereThe military establishment stuck with the .223 round. Though problematic in thick jungle conditions, it was useful in open field (snow to desert) and some urban conditions in that it was very accurate, but better yet, when it hit human targets it tumbled forward into tissue and shattered creating large, internal wounds. This was confirmed in later tests on special gels that simulated the consistency of human tissue. Another "nice touch" was that the bullet would sometimes ricochet off bone and bounce around inside the body, shattering in tiny hard-to-remove fragments (which promoted internal bleeding) and ripping sizable hunks of internal tissue away (for good measure)
I have heard this from several people in the military as well. From what I have been told that using a heavy grain (60+) in .223 Rem (5.56mm) in a rifle with a twist slower than 1 in 10 will cause the round not to fly all that stable and that when it hits something, flesh in particular, the round will start to tumble end over end in effect becoming like a flying buzz saw.Rammstein said:I asked my cousin that same question.
He was a medic platoon leader in Iraq and A-stan. He told me he would much rather get shot with the 7.62x39 than a 5.56. He said from what he saw the 5.56 created a much more devastating wound than the AK round.
