Can you spell cavitation?

I don't think you can contribute much of that to cavitation.
 
My take-away to that: Never take a gun to a shark fight!
 
Could have been worse... an above ground pool and a big mess.

Actually, I've heard that a VERY high speed bullet will only fragment when it hits something like water, but a slower speed one will go a fair (small) distance.

Urban legend.

The Mythbusters put it to the test.

They started with 9mm pistol and worked up to .50 BMG. Fast rounds did penetrate.

Not the episode I saw.
 
I gotta call BS on the busters. That's way too small of a splash for a full-load 50BMG in water at point blank not to mention AP isn't going to have a copper jacket.

As a suthrener, I should know. :wink:
 
Not that I know anything about AP rounds, because I absolutely do not have any old U.S. Army surplus AP rounds laying around, but I do believe there were some old ones that had tungsten carbide cores in lead with copper jackets. Yes I know that was a run-on sentence.

Our Walthers are stainless but I wouldn't be inclined to purposely dunk 'em anyway. :nonono::sick:
 
As a 50 cal and MK 19 gunner on 2 deployments I can say that standard AP rounds have copper jackets. The steel cores in the ammo need the copper jacket to pickup the rifling.....The only non jacketed rounds for the .50 cal that I am aware of are SLAP and SLAP-T....those are bare .30 cal tungsten projectiles in a .50 cal plastic sabot (I have 1 of each in my collection from Afghanistan)
 
I hear ya (and of course defer to your experience) but they show the jacket and never mention anything about the core. If combloc X39 steel core crap can go through an 8" live oak tree at point blank I would imagine an AP 50 BMG at point blank would go further than they say especially after it shed it's jacket. Them rounds you mention had a colored tip, right? Their's don't. What they have appears to plain ol' FMJ. The splash doesn't look big enough either for a full load either(IMHO of course) not to mention I would NEVER want to fire a 50 indoors no matter what type of hearing protection I have. I find it hard to believe a 50 expended all of it's energy in only 3 feet especially considering the size of the splash. Whatcha think? 600grn @3000 is a power factor of 18000. I cant see being "safe" at 14" of water with that.
 
Billy, made me get the TM out for ya. Yes most ammo is color coded. As for the lack of penetration in water I was thinking about the High speed water skiers that I have seen. They tend to skip on the surface when they wipe out. The density of the water compared to the speed of impact may change the game a bit. Also, bullets ain't designed for shootin in water

I'm a water skiin' fool, that stuff is nearly as hard as dirt when ya hit it at speed... I've had broken ribs and shoulder dislocation to illustrate the fact. :nightmare: :eeek:

"Angle of incidence" is another factor. Even the upper atmosphere can be "dense" when spacecraft reentry velocities are considered.
 
Water skied all my life. I am, after all, from south Louisiana. I still find it very hard to believe.

O.K, which one 'na you guys wanna dip down" inches while I shoot at ya? :grin:
 
I pick "feet" rather than "inches".

...and at 18 I was a 36 off on a Dick Pope ~WOOD~ Cypress Gardens stick.
