Lots of guns are capable of firing underwater without damage.

That pictured above are hollow point bullets opened up

where im from we dub them as "cop killers"

Looks like you hit the hornet's nest about the cop killer bullets that don't exist....

Nothing about a hollow point makes them more effective on Armour than a normal round

The irony is that those can save your life. Yeah, they hit harder, but they tend to penetrate less. You'll be glad if one of them gets stuck in your sternum instead of nicking your aortic artery.

Why shoot people to save their lives? Are you mad?
User avatar #182 to #118 - Zarke (01/31/2013) [-]
And I didn't say anything about shooting someone to save their life, but rather your chances of surviving if you were shot yourself. Maybe I worded it poorly, but I was saying that there are some factors involved in the terminal ballistics of hollow-point rounds that detract from their lethality in some circumstances.
User avatar #181 to #118 - Zarke (01/31/2013) [-]
There's a difference between "lethality" and "stopping power". A .22LR is plenty lethal. It'll kill you eventually, but it's not going to stop someone from beating your face in.

Shoot faster then

Yeah, that's what you're supposed to do, no matter how much of a "cop killer" your round of choice supposedly is.
User avatar #198 to #197 - liquidz (02/02/2013) [-]
But but, all the arm chair commandos must be right!?! Why else would they have a .45 1911 instead of a "tiny" 9mm with 16 round mags...

By their logic, just go for 7 rounds of .50AE and hope the problem ***** itself away.

Instead of thumbing you down I shall explain. Ahem...

Modern cartridges are airtight and are already surrounded by enough air inside the casing to properly ignite the propellant inside. When the striker hits the priming charge on the back of the round the propellant combusts causing the bullet to leave its casing. Granted, discharging a firearm underwater is not ideal as the gif no doubt showed you, and can cause issues when reloading.

That's not the real explaination tbh.. gunpowder cointains a mixture of sulphur, charcoal, and potassium nitrate. The potassium nitrate acts like an oxdizer, the sulphur is there to give a more stable and smooth reaction, and the charcoal is the fuel.
So in fact, gunpowder can in theory ignite in total vacum. No oxygen is needed :)

I am chemical engineer, and I like to be a douche nerd.

A gun was designed to fire rockets instead of bullets, eventually speeding up to bullet velocity but useless within a few feet. It could be fired underwater and in space.
User avatar #100 to #19 - Zarke (01/31/2013) [-]
Gyrojet. They're called Gyrojets.

I'd like to see that project revisited. Maybe in the form of saboted Gyrojet shotgun slugs, which may avoid the manufacturing flaws noted in later Gyrojet ammunition, and doesn't require any specialized firearms.

Imagine how awesome that is. Minirockets from a shotgun.

Gunpowder and like explosives still require oxygen to ignite, of which there is none in space.

I believe this gun was designed quite a few decades ago, though.
User avatar #42 to #41 - somenerd (01/31/2013) [-]
That is incorrect. Oxygen is contained in the powder itself and inside the casing. That means that no external oxygen is needed.
#44 to #42 - pxthreezerothree (01/31/2013) [-]
Hopefully not in gaseous form, because the casings would rupture due to the vacuum of space.
#48 to #44 - somenerd (01/31/2013) [-]
Most of it is in the powder. However, the pressure of space would not be enough to rupture a brass casing.

User avatar #79 to #48 - liquidz (01/31/2013) [-]
Space is a vacuum, ie no pressure. If the casing has air in it, then it has pressure inside of it, and will expand to escape.

Will it burst or not, not sure, depends on the amount, casing thickness, etc.

But I think it would be more likely the air would be forced out in space before it could even be used.

It needs to be tested either way.

.998, you fool! .998!

The 998-caliber Goldwyn-pattern Astartes Bolter rifle. For when 50-cal heavy stubbers just won't do the job.

Curses! I thought it was .998, but I wasn't sure, so I went on the wiki and it told me .75!

Wait, that was just for a standard Bolter, not an Astartes Bolter
#53 to #51 - krasnogvardiech (01/31/2013) [-]
Oh well. Them Space Marines always do have to make things bigger for themselves. I prefer a good old 16-inch Battle Cannon myself.
And these tanks have Combi-Bolters on the sides! ELEVEN BARRELS OF HELL, at your service!

Hellstorm cannon. Nuff said

wait what. Shooting that gun would destroy the tank and probably kill everyone around it from the concussive force. unless it's a laser, then it's pretty cool. Erm...

Emperor's Blood, look at the size of that thing! You'd better be packing lascannons, or you better have armour if you don't have them.

doesnt it only work on things larger than 9mm? If i'm thinkin right, 9mm has a small enough surface area to not be ripped apart upon contact
User avatar #25 to #11 - Bion ONLINE (01/31/2013) [-]
Most handguns can shoot underwater, as long as the hammer isn't exposed (like a revolver). The gun can still function, and it has nothing to do with the bullets, but the water friction can slow the hammer down to the point that it won't set the bullet off.

When shot INTO the water, the gun will either be so strong that the bullet shatters on impact, or it's velocity will die out after about 2 feet deep. Either the case, guns aren't that dangerous when shot into water.

Try shooting a gun with the barrel and only the barrel submerged...
User avatar #20 to #11 - Mr Ronok (01/31/2013) [-]
water will break up anything over a certain feet per second. i forget the number, but there isnt a gun that fires under it
User avatar #17 to #11 - twofreegerbils (01/31/2013) [-]
Water stops bullets, period. And quickly at that. Caliber is irrelevant.
#12 to #11 - notyaoming (01/31/2013) [-]
Pretty much everything they shot into the pool broke apart after a few feet. It isn't surface area, its that its moving so fast, the drag breaks it apart.

Most weapons that fire cartridges can shoot in space and underwater because they have oxidizer in them.

Mythbusters did a bunch of test-firings of guns into water to see if the bullets whiz around like in the movies. Turns out that the larger the caliber, the less distance it penetrates the water. Even the .50 Caliber round disintegrated milliseconds after hitting the water

User avatar #168 to #29 - meganinja (01/31/2013) [-]
I wonder how the .50 caliber round would have fared if they actually fired it underwater. As I recall, they fired the rounds from above the water into the water. This led to the bullets striking the surface of the water, which at that speed, is comparable to hitting concrete, which would cause bullets to disintegrate upon hitting the surface.
User avatar #99 to #29 - Zarke (01/31/2013) [-]
It's more of a matter of velocity rather than caliber. A heavier round would fare better under water, as the resistance from the water is proportionate to the velocity the projectile. Reduced drag + increased momentum = further travel time. Granted, that doesn't mean much if the round is travelling over 2700 feet per second, as with that .50 BMG.
User avatar #109 to #99 - waffies (01/31/2013) [-]
Ah, well i guess i didn't connect that it wasn't exactly the caliber, but the velocity. It just so happened that in their tests each new weapon had a larger caliber, the velocity must have increased too and i either didn't hear them say it or they didn't mention that bit
User avatar #83 - Dap (01/31/2013) [-]
0 to ~825mph to 0 in 18 inches.

No wonder the bullet gets absolutely ruined haha

in one of the myth busters episodes they were testing a myth where they shot the water from the surface to see how deep it will go... the bullet just blew up as soon as it touched the water
User avatar #22 to #15 - Bion ONLINE (01/31/2013) [-]
They only said that part. If the gun was powerful enough, it would have destroyed the bullet on impact.

The guns they used weren't that strong, and they found that after about 2 feet of water, the bullets lose all of their velocity.
