I know what I saw, fool, and the trees probably were red maple of the swamp maple variety, not the onamental lawn variety. I was astonished and I didn't think it would penetrate even the first tree. It could be because the trees were getting plenty of water, but I wasn't that close to that stream and was on a slope going towards it. I also thought the bullet would start to tumble and there was no evidence of that happening. All four holes were the diameter of the bullet, though the back of the trees was busted out like an exit should be.
What part of that round going right through a person and hitting another person is too hard to understand. Those NATO rounds were known to hit a bone and travel to weird places in a human body until exiting. You can get shot in the chest and have it come out your leg. I doubt if normal ammo is that bad, but those military rounds could do some weird shit and I have shot plenty of them. You could buy them for around $0.07 to $0.10 per round back then and the military surplus stores had plenty of rounds to sell.
Shooting an AR-15 off in a populated area is not safe. That round will go right through the walls of a house like it's nothing and a shotgun projectile would slow down. Use aught or double-aught and not deer slugs. Use a large dog and a shotgun, if you truly need protection from a home invasion and remember you don't have to shoot someone, unless you really have to. The good dog would keep a home invasion from happening, so use your brain for a change.
What I see about right-wingers is always the same bullshit. Nothing is ever what it is, to a group of fools like you people. You're the Ritalin Republican Party.
You are full of poo as I said. It is physically impossible for any 5.56 mm round to do what you described.
Here is just one of many tests showing the poor penetrative capability of 5.56 ammo. As I said, you are a prevaricator of the first order and full of dung...
223 Rem. gelatin only 9.5" two pieces
.223 Rem. wall & gelatin 5.5" * fragmented
.40S&W gelatin only 13.5" mushroomed
.40S&W wall & gelatin 22" * no deformation
.40S&W wall & gelatin 22" * no deformation
.40S&W wall & gelatin 19.5" * slight deformation
12 ga. wall & gelatin 27.5" mushroomed
Real World .223 Testing
The penetrative capabilities you are describing are for a 7.62X51 NATO round (and even there you are full of crap as they can't punch through two trees, but they can punch through one) and yes, that round will punch holes through several houses in a block before it stops.
