Thread: How well do bullets swim?

the US NAVY actually had underwater 9mm rounds for shooting underwater used in MAC 10 submachine guns during vietnam war.

when i was a kid we used a 1/4 stick of dynamite for fishing.......the stunned fish would rise to the top and we'd net them. don't think that's permissible today! lol

I had a gold claim for a number of years... judging by the sheer qty of lead buck shot and bullets I collected... I can attest that Bullets cannot swim... they drown... quickly.

Used to walk along the river shooting eels with a 12 g. Would stun them then gaff them out. Cousins would dive in with a Winchester .22 pump and Fire it under water, had a perfect cylindrical bulge in the barrel. Dad and his brother used explosives off the Carrington Bridge outa Masterton, the crater was still there on the southern side, last time I looked, dad couldn’t believe the bang and rocks falling around him, as he netted jellied fish down stream.

Indeed, They banned kids from being able to use dynamite. It does not fit with their bubble wrap policies now.

That is also how "shooting" fish works. It is not the bullet hitting the fish that stops it. It is the shock wave in the water created when the bullet expends ALL of its energy in the few inches of water that makes a hydraulic impact on anything nearby...

strangely enough, back in the late 90's I used to buy the odd stick of gelly from wrightsons. Just sign in the book
$2.50 a stick/plug and 5 bucks for an electric det. you couldn't buy fire crackers though lol.
safety fuse and the applicable dets was a lot cheaper but it is a beyatch to light.

To the OP, if you want a nice brain ache, this

I can't be bothered reading it myself but I remember one theory that bullets with the best chance of going furthest and straight underwater have blunt or rounded noses. They set up a cavity of air to travel in, reducing drag, which also allows the stabilising effect of rifling to continue to a degree. I think this is also the theory behind dangerous game solids and FMJ always having blunt or rounded noses, not spitzers, better penetration in animal flesh which is a large % water.

I'm really shocked to see the video. But why the bullet doesn't speed up in the water?
