Is it safe to shoot wet guns?

Discussion in 'General Gun Discussions' started by alfon99, Jul 5, 2013.

  1. We should mention that when draining water from a barrel that is submerged or even partly filled with water, it is advisable to point the muzzle down, and extract the cartridge enough to let air get around the bullet and case to allow the water to drain out. This was a standard practice in RVN, especially with the "new" 5.56 rifles. Smaller bores are more affected with water than large bores. You can guard against water in your barrel by taping over the muzzle before trekking into monsoons and such. The first shot will blow the tape off the muzzle. Condoms can be used to cover muzzles with flash hiders, etc.:D

    There is a simple solution. I keep tape over the the muzzle and spare tape on the barrel. Pressure building up in front of the bullet blows the tape off before the bullet gets to the end of the barrel. Accuracy is not affected and it not only keeps water out, but any dirt, snow, and pine needles even if you drop your gun muzzle down.

    I'm often asked by hunters/shooters when I meet them in the field or range about it. I always start off by telling them it is to hold the barrel together because of the hot loads I use. Then I tell them the truth.

    Yeah, I can't trust a video of someone trying to sell me their product by showing why the competing product is not as good.

    All of these "As Seen on TV" product commercials crack me up. They show people struggling to do the most mundane of tasks in order to sell some cheap bauble which supposedly makes it easier.

    I'm just fuzzy on the physics. IIRC, water can't be compressed. So I suppose on the one hand that enough built up water pressed hard enough by the advancing bullet will slam into the air in front of it, creating a "water bullet" down the bore and spiking pressure likely causing a bulge. But does this actually happen outside of submersion? The video would suggest so, but it's not clear what they did there. And on the other hand, bits of raindrops and even lots of condensation in the bore have never to my knowledge caused any harm. The water is going to be heated to steam almost instantly presumably, or just shoved out the end.

    Would this work for shotguns? Of course more tape is needed.

    well watching what happened,the explosion of the projectile causes the bolt carrier and the buffer to go rearward.if the buffer tube is filled with water,the gas can go nowhere but up,blowing off the top of the receiver is one scenario.

    Yes. I keep all of my guns barrels taped the entire hunting season. I take it off after. As I said earlier, it is not just for water. Lots of other debris can find it's way into a barrel. This has saved a couple of hunts where rifles have been dropped and landed muzzle down in mud.

    I don't think a few drops of water in a barrel are going to be dangerous. The military has been fighting battles in jungles, rivers, and rain for as long as we have had rifles. But it can't be good for anything. Tape is an easy cheap preventative.

    I have seen.pictures of guns with busted or blown receivers and barrels from water,snow and mud. I would not roll the dice on this one.

    This is a great thread-especially considering it must be monsoon season down south this week. got soaked at the range and wondered this myself. i guess one just needs to make sure the ammo stays dry..? i reckon wet primers are probably not a good thing:)

    Firing a submerged gun is a completely different thing from firing a gun out of the water with a significant amount of water in the bore. A submerged gun has water pressure all over it as well as inside it. A gun in the open air with water in the bore has a big 14 pounds or so of air pressure on the outside and an obstructed bore on the inside. It is pressure differential that causes the problems with water in the bore. The amount of water in the bore and the pressure the cartridge is working with will determine whether the gun fires safely, ends up with a bulge in the barrel, or destroys the barrel, the action, and/or the shooter. The Army issued plastic caps that covered the muzzle and flash hider on M16s when I was on active duty to prevent damage from bore obstructions like water, mud, ice, and snow. BTW, the smaller the bore for a given pressure, the more likely it is for water to cause problems, in my experience.

    Odd, I couldn't find your video of it in YouTube.

    I managed to pick up some surplus plastic muzzle caps. Great fit on M16/AR16 pattern barrels with muzzle devices attached. Made by a company call Caplug. Seen their work in non-firearm products too.

    That video linked by Sam1911 is for a youtube channel called SmarterEveryDay, and he does a great job giving us gun guys a good reputation with academic types.

    I've always heard that condoms have been used over muzzles for many a year. Wasn't that a WWI trick?

    an AR should have a little hole in the screw that holds the buttplate on so water can get out when it is fired

    It depends. When in wartime there is no timeout for weather. When given a choice opt on the side of safety.

    In my case I don't think muzzle covers are an option, I live in Uruguay and in the middle of nothing. So I guess I will tape my gun barrels. Here even condoms would be hard to get. Last night and today in the morning it rained 100mm. That's a lot! And there was a huge thunderstorm. We went hunting last night but we came back home because of the lighting.

    The difference in safety equipment is because HK knows that the Colt will fail and their HK won't. This is a post production video of previously conducted tests.

    The video explains the test A parameters include submersion with an open bolt and closing the bolt while under water.

    +1 for using tape (et al) to cover the muzzle! I have used electrical tape over the muzzle ever since the day we came in from hunting and my buddy ran a cleaning rod from the breech of his 300 mag and had to force out a 4" piece of branch that had gotten stuck in there.
