Advanced Underwater Bullets For Shark Defense

High speed low drag… literally:

Pretty useless video without any info along with it, but impressive to see the bullet penetrate 13 water jugs, a black plate of some sort and then a 14th jug behind it.

I’m confident in it’s ability to slay Great Whites next time I roll backwards out of an airplane over the pacific to start off some OP.  As long as they make them in .45 i’ll be happy.

PNW Arms is the manufacturer.  Their website is made to look professional, but is actually incredibly shitty in function and useful content.  I guess we’re supposed to care enough about this bullet / cartridge after today in order to come back again and again until they post more info on it. *eye roll*

Thoughts?

    I believe PNW are the US manufacturers while DSG do the R&D…

    1. Submarines with CIWS?

      1. Submarines, surface ships too, could also potentially be loaded into existing Phalanx and Goalkeeper systems to defend against mines and torpedoes.

        It seems that APFSDS is a better idea for larger calibres though: http://www.ctechdefense.com/30mm.html

        High velocity and sectional density are important when you’re going through a lot of water.

        On a small arms level, you can certainly imagine the benefits of being able to shoot effectively from the surface below water and vice versa, Somali pirates should be afraid, very afraid…

  2. Supercavitation is the process by which the nose of the projectile makes the water so turbulent that it “flash boils” and the projectile passes through a pocket of vapor. The reason the bullet passes through so much water is because only the tip of the bullet is touching the water, the rest of the bullet is moving through steam. Very little drag so much better penetration.

    This bit of science brings me to my next point: I want to see what this does in gel. I wonder what kind of wound channel is produced by the supercavitation process. I can imagine it punching a pretty large hole through a target because of how it works.

    1. Flesh is mostly water…

        Yes but flesh has a much higher flash point

    2. Not traveling well through water is the most important part about bullets hitting flesh.

        “Not traveling well through water” is a precondition for making big holes in things with conventional technology.

        This technique *could* just give us more damage per joule, which would mean we could either make effective, inexpensive, low-recoil self-defense ammo or we could make bullets that turn a deer gun into an elephant gun.

        I’m okay with either, really – being able to carry a .22 magnum without being undergunned would be nice, and users of the FN P90/5-7 and the AR-57 would all immediately rejoice I’m sure.

        But lest I be accused of getting ahead of myself, I’ll wait for proper testing before I get excited.

    Up until now? Try early 1970s: http://www.youtube.com/watch?v=x-P578pnctU

    1. It’s not super cavitating, not great in air, not practical and needs a fancy ass gun.

      1. the latest iteration is effective in both air and water, and can fire both conventional ammunition and a new type of round for underwater shots: http://world.guns.ru/assault/rus/ads-dvuhsredny-e.html

  4. So we’ve seen it shoot through water, not under…

  5. i’m skeptical. probably for IP reasons or whatever, but we never saw the projectile after it did all that cool penetrational nonsense. also, how do we know it wasn’t something else. it could be a crackhead that got ahold to the wrong stuff and it told him to get up on that jug and play a supercavitating bullet.

  6. If anyone is interested they also have 300 Blackout ammo for what I consider very good prices. Usually the subsonic stuff runs about $1.25 / round and they have it for about $1.00 / round. Good deal.

    I don’t get what you’d need or want this for

    What you would neef this for? Fighting underwater of course! Or perhaps a new kind of fishing. I must admit i kind of want some, though for my collection not so much for Shooting

    They probably never heard of Batman’s shark repellant bat spray :P

  10. YAY! Now we can have a more efficient james bond vs. spectre underwater battle!
