not a Glock. Seen one of someone shooting a glock underwater.

Cool picture. The Ammo Encyclopedia 4th edition shows Russian cartridges meant for underwater combat. They look like bolts.
Is that a...
Is that a .45? Cool looking. Wonder what a .44 or .500 mag would look like?

I bet clean up is a snap!

look at the difference between the cone shaped shock wave produced by the escaping gas & the bullets peak velocity at the muzzle and the following ones, produced by the velocity of the bullet noticeably decreasing as it travels in little more than a foot increments........... It surprised me that it dropped off this sharply............ and if it retained enough energy to puncture a large, thick phone book 10' from the muzzle.

I don't know about the energy but I recall years ago a guy told me if you are 4-5 feet underwater it would not likely do much damage. Not sure I'd want to be that test case.
Never hear any discussion but isn't a bullet also spinning at about 60,000 rpm (nominally) at the muzzle ( using 1:12 rifling - 1000 ft/sec X 60)? When I see images of expanded bullets and think this they seem like they could do some serious damage to someones innards.
The first bubble reminds me of the old Jiffy Pop popcorn cookers for cooking over an open fire or stovetop.

It's been tested. The higher the velocity the less the bullet travels underwater. If shot from above a rifle round practically incinerates as it hit the water. Slower moving bullets, like a 38spl, actually penetrates deaper

It is much simpler than you are trying to make it.
Using your example, the bullet makes one complete revolution every 12 inches. So if it goes through "media" that is a foot thick, it turns (at most) once.
I say "at most" since the rotation, like the velocity, will decrease (perhaps even go to zero) as it traverses the media.
