    Shooting a rifle underwater



    I guess what I don't understand, is if gun powder needs oxygen to burn, how does it ignite?

    This is all guess work understand. But Im guessing that there is enough oxygen trapped inside the casing for it ignite and burn. For a short period of time maybe??

    Ammo isnt air tight or water proof obviously but the ammo isnt being submerged for a long period of time in that video from the looks of it.

    And I could be totally off in left field too

    there is some oxygen in the case but even if there wasn't gun powder will still burn just the same, even if a round is loaded in vacuum.

    Nitrocellulose (smokeless) powder contains it's own oxygen and so does block powder. the oxygen is bonded to other chemicals in solid form just like a solid fuel rocket.

    in a nut shell:

    black power is charcoal, saltpeter (usually potassium nitrate KNO3, the O is oxygen and there is three present in each nitro molecule) and sulfur.

    the charcoal is the fuel, the oxygen is in the nitrate and the sulfur serves as a bonding agent.

    Nitrocellulose powder does not need sulfur because the fuel and oxidizer is bonded. the left over sulfur in black power burn attracts water and becomes sulfuric acid which can corrode the bore.

    it's a bit more complicated then that and there are different formulas but you get the idea.

    nitroglycerin, more correctly known as glyceryl trinitrateis the same way, the glycerin is the fuel and the nitrite has the oxygen. mixing it with "clay" stabilizes it and is called dynamite. Alfred Nobel discovered the process, he was upset that his invention was used for war and therefore created the Nobel peace prize.

    Trinitrotoluene or TNT also uses nitrate to provide oxygen. despite that AC/DC had told us, TNT is not the same as dynamite.

    so pretty much all explosives use nitrate to provide oxygen, RDX or cyclotrimethylene trinitramine, active ingredient of C4 is no different.

    nitroglycerin was later discovered to relaxes blood vessels is used to treat chest pain, Nobel was shocked that his doctor wanted him to ingest explosives

    it self oxidizes
