They had a lot higher rate of fire.
Fire stops under water because water deprives the fire of oxygen, which is essential for combustion. Without oxygen, the chemical reaction that sustains the fire cannot continue, causing the flames to be extinguished.
An ordinary fire would not survive under water, for a common fire requires fuel, oxygen, and heat. under water there would be no oxygen available, and the heat would be conducted away too quickly. HOWEVER oxy-acetylene gas cutting can be done under water, for we carry our oxygen with us. And bulk magnesium will burn under water (incendary bombs).
Keep it under water

If you are asking "WHAT" not "Where" is the most powerful under lever .177 air rifle. Then I suggest the "Hatsan Torpedo 150 air rifle." I comes in at around 1250 FPS where as most of the other under levers fire at around 950 to 1000 FPS. However Under levers are not the most powerful air rifles. The PCP (PreCharged Pneumatic) Class of air rifles are the most powerful air rifles. An "Air Force Condor and the Evanix Rainstorm" fires a .177 cal pellet at 1300 FPS.
