    Are you talking about the one where they fire out of the water into it. If so at a 30 degree angle it was about 3 feet.

    no, they submerged a gun underwater and fired it

    Hello, I have an underwater shooting video, and although the guy doing it is kind of a dope, they do show the guns (all hand guns) shooting underwater and all of them worked. The lethal range is rather short though, as shown by shooting a pumkin underwater.

    Saw it - the only one that didn't work was the
    double barreled .12GA - it blew the barrels and
    broke the gun/stock.[:0]

    yeah, but they didnt say why. why would a shotgun explode like that but the other guns didnt ?

    I can't think of any reason why a firearm with well sealed ammunition would not fire underwater. I would think that the mass of water inside the barrel (which would be very heavy compared to the bullet) and ahead of the bullet would cause a severe drop off in velocity as well as range. I'm guessing that the shotgun blew apart because it's bores were very large and if the barrels were long enough this would equal a tremendous amount of water which created too much pressure for the thin walled barrels typically found on shotgun to withstand.

    Two points:

    1. Water is a much better conductor of sound than air is. If YOU are underwater, and you fire the gun underwater, the increased sound impulse will rupture your eardrums. NOT fun.

    2. Some guns will function underwater, some won't. In some cases the increased resistance from the water slows down the hammer/firing pin/etc to the point where the gun wont function. In other cases the water filling the barrel can dangerously increase pressures.

    I wondered about this after seeing mindhunters.

    I remember an old TV series, Sea Hunt. In one episode, there were these bad guys that were up to some sort of underwater mischief, and one of them took a .38 revolver along on the job, figuring to use it if he had to.

    During the action, the guy with the .38 did fire it several times, with no apparent ill effects, but the bullets only went a few feet.

    I know, nowadays no live ammo is allowed on TV and movie sets, but this was a LONG time ago, and I don't see how the effect could have been faked.

    I also saw the Mythbusters episodes mentioned. I wouldn't have fired a gun underwater even before seeing the shotgun blow up.

    eh...dumb question here....why would you want to shoot a gun underwater? are mexicans swimming across the border in scuba gear? Is fishing with a line and a lure loosing it's apeal. is someone going polar bear hunting? I can just hear the next thread....
    Whats the best gun to take while hunting killer whales under water?
    22 if you hit em right/ I think a thompson contender...oh those suck you gotta have a Smith 500 mag...
    what if a great white shark attacked could you kill it underwater with a slingshot?...no wonder we turn to soft core porn on this sight where that remote girl?[:D]heres a good idea, if albert asks a question, just ignore it[;)]

    I did some research on this years ago trying to come up with better power for spearguns. I will not go into the specifics, but firearm cartridges do not work for anything farther than 2 feet away.

    Nothing beat rubber bands (abet special rubber bands), for powering spearguns.

    They mentioned the 9mm did not eject the cartridges under water, also they had to get all the air out or it would blow up.

    What about shark billies? A sort of a bang stick. Anybody ever see or use one? It is a long stick with a barrel on it that holds a 12 gauge shotgun shell. To make it work, you jam the muzzle against the shark ahd the shell fires. Looks like if the Mythbusters' shotgun would blow up, a shark billy would, too.

    those are also called a bang stick the one we keep on the boat exposes the end of the shotgun shell at the muzzle no barrel to blow up

    I guess it's because there is a LOT more water in a 12 gauge barrel that you need to accelerate. Hence a higher pressure.

    As you usually have unobstructed barrels and the shotgun-barrels are dimentioned for a lot less pressure - adding about 1/4 lbs of water to the "load" can't be a good thing.

    Yep - we used to make 'em - back when we were teenagers. We made/tested most of the
    normal calibers from ..38 to .12GA. The .45's & .410's were the most popular.

    We made them with 3" stainless steel stock - using a floating star firing mechanism
    - very simple to make and use. The hardest part was turning the barrels - our buddy's
    dad was a master machinist for local Solar Aircraft. We had a full machine shop of the
    BEST and heaviest quality set up in one of his barns (his father's).

    The reason there was no problem with blowing barrels was that the stainless is HARD
    and 3" is much too short for those kinda of problems.

    The mechanics behind bangsticks is simple - hit the shark on the top of the head and the
    bullet opens up the tough skin - the rapidly expanding gasses do the damage.

    100% effective. There were no concussion issues.

    We used to sell them to young naval aviators who were shipping out to the PI and
    quite a few to Kwagelin, at the time. We sold them for $60 each - quite a nice profit in the early 60's![:D]

    I have the underwater cups in all my Glocks and have not had to use it there yet. I will let everyone know when I do.

    shot guns have a thin walling ,simply just not the same quality if a rifle/pistol barrel & bore.
    i once fell over used a 12g as a walking stick one winter ,a fox ranout & i took a shot, dam thing, the mud froze & the side /side popped open, simply f***ed![:D]

    I tried shooting my trusty hand cannon underwater but it didn't work. Bad matches, I guess. They said "strike anywhere" on the box but that was obviously a lie. [:(!]
