BB in nose of JHP

[puma guy]

back in the early 80's there was a law enforcement round sold in a shiny black box. The name was "Exploders" ..

it was a very large hollow point round, capped with a magnum pistol primer and sealed with some type of red sealant.

dunno if there was anything under the primer (powder, etc) but they made one heck of a hole when they hit.

I guess we were ahead of the times in the sixties. As far as something under the primer, FFFFg comes to mind as a possibility.
This is of course all theoretical!

Think of the marketing you could have done!!

all I remember about these were that there were 20 in a box.. the rounds were packed in foam, and our Class 3 dealer brought them when he came calling..

'cept in .357

Interesting. They look almost like I imagined a 165 gr JHP .357 would look like with a primer inserted cup out! I guess they could have put the cupside in, leaving a little space in the cavity, Huh?

As I understand it, hollow points expand due to the tremendous hydraulic pressures that are created inside the cavity as the bullet plows through the body (which is mostly water).

Closing off the cavity with a BB would be a quite effective way of keeping fluid OUT of the cavity. I think it would work just like a FMJ round, at least until the BB got knocked out of the cavity.

Think about it. If it worked, SOMEBODY would be selling ammunition made that way.

I believe the Corbon ball collapses (or maybe it shatters?) and allows the hollow point to fill with fluid.

I still dont understand how the Hornady Critical Defense round works with the hollow point full of rubber, but every review on youtube makes it look like a really good round.
Wouldn't a piece of rubber in the hollow point cavity to the same thing?

The filling in the cavity on that bullet isn't solid rubber, but soft and acts like a fluid on impact. You're basically pre-filling the nose of the JHP with a flesh analog that gets the expansion going, even on impact with fabric. This solves the problem of lack of penetration when first impacting a fabric barrier that would fill the cavity prior to hitting soft flesh, impeding the bullet from expanding.
