Once you get your gun underwater, the barrel almost immediately fills up with water. All that water in the barrel has to be pushed out by the bullet. Depending on the length of the barrel, the weight of all this water might be several times heavier than the bullet itself. Pushing this water significantly reduces the muzzle velocity. Guns are designed to work in standard atmospheric conditions which means that being submerged in water causes trouble with the action of most semi-automatic handguns and rifles.
Water is obviously more dense than air, when you try to fire bullets underwater, the weight of the water slows down the bullet making it lethal in just a few steps away unlike when you fire it above the surface. Another thing is when the water enters the cartridge, the gunpowder gets soaked and in the end may result in failure to ignite. That being said, yes you can fire your guns underwater BUT your gun may not work for the very purpose you need it to like underwater defense.
Ammunition : The problem starts here. Modern ammunition is watertight and you may still fire them outdoors during heavy rain or high-humidity season. So before firing ammunition, you must put into consideration how long it was submerged underwater. When the powder is soaked, this component easily gets dissolved thereby causing problems for the gunpowder to ignite. Action : Guns being submerged underwater may disrupt the action of most semi-automatic handguns and rifles.
The expended casing may have problems with ejecting correctly or the water may slow down the action of the gun as you fire them. Good thing is, this is not true to all types of guns as this does not apply to revolvers and reportedly with the AK Revolvers should function more reliably than any other firearm underwater. But the reason Mr Wahl was not injured by the bullet is because water is times denser than air, which stops it from travelling so far and so fast.
It is not the first dangerous stunt Mr Wahl has attempted - previous experiments have seen him soaking himself in water before trying to roast himself in a fire.

If you're wondering how it's even possible to shoot a gun underwater, gunpowder contains oxygen — a key element in the firing process — the gun still goes off exactly as it would on land.
And instead of barreling towards Wahl, the bullet slows and falls to the bottom of the pool. You can watch the entire experiment here or below. Follow Tech Insider on Facebook and Twitter.
For you. But even though Wahl probably did his homework about shooting a gun off in the water, his face showed he was more than relieved the bullet sank. But the gun isn't the reason Wahl is still alive, it's the bullet. Water bubbles followed behind the bullet as it sped towards Wahl, but momentum was lost before it reached the halfway point and gracefully sunk to the bottom. Wahl dived under the water and brought the bullet back up to the surface, holding it high above his head like a trophy.
The casing of a bullet is waterproof and the firing pin collides with it causing the gun to fire. Once the gun is fired, all of the energy produces hot gases that launch the bullet out of the firearm.
Guns work underwater the same way they work above water, according to Discovery Science Channel. Traveling through water, a bullet will barely hit 2 meters, which is because water is times denser than air. The bubbles viewers saw blowing out of the barrel were created by the different pressures in the water. The bubbles viewers saw blowing out of the barrel are made from the different pressures in the water. In the front of the bullet there is an area of high pressure and behind it is low pressure, and in between is a vacuum of water that boils to create a small tiny cloud of gas.
