Myth Busters - No Firearm Penetrates 14-inches of Water [video]

It has been proven that no firearm can penetrate 14 inches of water, not even the magnum .50 cal sniper rifle with steel-jacketed bullets, so this means that if you want to be safe from any bullet just stay under 14 inches of water in a river or lake. picked by maxriter 2 months ago

I wish this would load while I'm at work, but it wont. I think I can find a gun capable of doing that though:
A-10 Thunderbolt

Although the A-10 can carry considerable disposable stores, its primary built-in weapon is the 30 mm GAU-8/A Avenger Gatling gun. One of the most powerful aircraft cannons ever flown, it fires large depleted uranium armor-piercing shells. In the original design, the pilot could switch between two rates of fire: 2,100 or 4,200 rounds per minute. This was changed to a fixed rate of 3,900 rounds per minute. The cannon takes about half a second to come up to speed, so 50 rounds are fired during the first second, 70 or 65 rounds per second thereafter. The gun is accurate; it can place 80% of its shots within a 40-foot (12.4 meter) circle from 4,000 feet (1,220 meters) while in flight. A two-second burst, therefore, will result in about 100 hits on a tank-sized target. The GAU-8 is optimized for slant range of 4,000 feet (1,220 m) with the A-10 in a 30 degree dive.

I've read elsewhere that the canon on this plane can only be fired in short bursts, because the recoil is more powerful than the thrust of the engines!

The A-10 is hardly what anyone would describe a 'Firearm'

I wonder what it is in water that makes it such a great backstop and do those same physics apply regardless of the speed of the projectile?

I'm thinking it's the two hydrogen atoms and one oxygen atom. :-)

Fine. What if I take off the cannon and slap a pistol grip on it? Does it count then?

Plain and simple: viscosity.

So there may have been some artistic license taken in the Normandy beach landing scene in Saving Private Ryan? That those people at least two feet below the surface of the ocean getting raked by machine gun fire, wouldn't have gotten hit?

It depends on the angle of the shot at well, though. if the shot is taken perpendicular to the water's surface than it will travel much further in the water than if it was shot at an angle.

No idea, but since you'll be in the shop anyay, make me one!
