I was a Glock armorer for fifteen or so years. Glocks will fire just fine underwater. Glock makes special striker (firing pin) bushings to ensure compression within the striker channel doesn't cause a problem. I worked on AR15s but was not a certified armorer. The word on the firing range was that an AR15 with a water-filled barrel would blow up. I don't know if it's true.
But here's your problem: Bullets will only travel a couple of feet (rifles) or inches (pistols) in water. I've tested high velocity rifle bullets fired vertically into water filled drums and even the .300 Win Mag is safe to fire to recover the bullet. Wear a rain coat. So... unless your submariners are firing with the muzzle in contact with the target, forget it. There's a reason SCUBA guys use spear guns. L |

Thanks Lazer. Yes, I understand that the bullets aren't going to go far - I was assuming/hoping they'd probably make it out of the barrel. I wasn't interested in hitting anything, only in demonstration. Any guesses on how the ammunition itself is going to hold up at (say) 1000ft (450psi water pressure) ?

All U.S. made military small-arms ammunition utilizes brass casings. I'm going to assume that at 450 PSI it'll show signs of crushing. It might still chamber in the firearm and would be somewhat safe to fire. Most ammunition manufactured in Russia, China and other eastern producers (for the AK47 and such) use soft steel for the cases. I don't know if it would fare any better. L |

My current 7.62x54R (Russian rimmed) mil-surplus cartridges are steel and lacquered to resist moisture. Some calibers (not enough taper) and weapons (tight chambers) should not use lacquer because they may jam in the chamber after firing. A typical example is 223 Remington, where Wolf brand decided to stop lacquer coating that cartridge.
No idea how well that lacquer seal would hold up in deep water. |

Thanks for the feedback. It's all much more complicated than when the idea first flashed through my head.

Lots of theory and guesswork. Most standard Military ammunition will work fine under water, though most automatic weapons will not - some will explode. The reason I know that most Military ammo works is that it is often used in power-heads used for killing sharks etc., when diving. I have had power-heads chambered for .308 Winchester, .223 Colt, .762 Nato and twelve gauge shotgun (SSGs). I have also seen a 9mm Browning Hi-Power explode when fired underwater. The distance traveled depends very much on the projectile. The Browning I mentioned was loaded with wadcutters, but full jacket with long tapered tips travel far enough and impact hard enough to kill gamefish.

Not sure that any of it helps my original problem, but definitely an interesting video to watch. Thanks! ETA: And now I know what people do if they don't write in their spare time. |
