That video made me think back to all the boring examples taught in my fluid dynamics course and how this would have been much better example to have used!

I know there's a Navier-Stokes joke in there somewhere just waiting to pop.

If I had access that camera, I would be more than willing to sacrifice a used Ruger P-89 to science in order to find out what happens when you do that trick with a JHP.

The Ruger extracts underwater and Glock can't get a reliable Gen4?

I don't care who you are, that's funny right there. :D

I wonder if his hypothesis about revolvers giving less energy to the bullet is true.

Yes. Assuming you were using the same cartridge and the same barrel length.

But, the Ruger is not perfection ( 4th gen).

We tried it years ago with a G17 and the federal 135gr Hydra Shock. It didnt expand at all. gun ran fine for years after that.

Hydra-shoks rarely expand anyway.

Hydra-shoks rarely expand anyway.

FWIW, that's news to me. There's a difference between getting plugged with 4LD and not expanding, and "rarely expanding." From what I knew, Hydra-Shoks over-expand in BG, and clog up with 4LD.

While a poor choice in service calibers, surprisingly, the .380 Hydra-Shok load is the only load in that caliber that will expand and make 12" in BG. Like it's bigger brothers it clogs up and doesn't expand with 4LD, which isn't exactly a bad thing for .380 if it does happen.

Sorry, tangent.....

To close the loop: I implied reliably and adequately. Editing the above post.

Tell me I'm not the only one who thought of this thread when watching the latest Archer...

My older 3rg gen G17 is reliable underwater with NATO ball ammo for repeated shots, I wouldn't try JHPs myself.

Huh.

You'd think it would have tried to expand in the bore. I wonder why not?

Now I want a high-speed camera and a fish tank...

I would guess its something to do with the pressure inside and outside the cavity being constant and/or equal or something.

The next 50,000 round test will be done underwater while Todd learns SCUBA diving......

Or maybe it hypercavitated?
