[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Anyone who says the AR-15 isn't more dangerous is lying to you.  The high muzzle velocity means that a small round causes [b]lots of damage including cavitation damage[/b], which makes less accurate shots more likely to sever an artery or turn a vital organ to mush.  Also the 223 tends to tumble a lot inside.

A hunting rifle packs a bigger hit, but the recoil is so strong that you can't stay on the same target and put round after round into them.  The AR-15 has low kick because the recoil is absorbed and turned into the energy to eject the casing and chamber the next round.  This allows you to stay on the target and put multiple rounds into it.  And the ability to fire lots of round means that an ordinary person can kill a lot of people.

And obviously the large capacity magazine gives you more shots between changing magazines.

So in short, a non-expert with an AR-15 can kill more people because the round causes lots of damage, but the recoil is light enough and the capacity high enough that you can get off a lot of shots.  [/quote]

Is that what happened to the first graders? "Cavitation"?[/quote]

Cavitation is the hole created in the body a few inches inside.

To get an idea of what it looks like watch episodes of myth busters where they use ballistics gel.

I couldn't find a great one for rifles but here is a comparison for pistols.

That pic isn't showing what you think it is.Gel is less elastic than tissue, this is one of the draw backs to gel testing and a major reason that gel doesn't represent what actually happens to tissue very accurately.

What you are seeing in that pic is what is know as the temporary stretch cavity, it is purely a result of the gel having very low elasticity. The darker line in the middle is the permanent cavity, and represents actual damage, not just stretch marks

Virtually all rifle rounds will create significantly greater permanent cavity than any handgun cartridge is capable of. Handguns simply don't have the barrel length for the projectiles to get up to the same speeds.

That being said, the .223 round isn't unique to AR15's, there are dozens of different rifles available chambered I'm that cartridge. So that doesn't answer the question of what sets the AR15 apart and makes it so dangerous. The reasons given so far are pretty universal to all modern small caliber rifles, they aren't things that make the AR15 somehow special [/quote]
