Hmm , Ammo.

Not sure if I should post this here but it's pretty dang cool so . . .


Can't say too much about the detail but some of my contract work has lead me to do some testing and R&D work with and relating to BMT's or Blended Metal Technology Bullets.

Anyone heard of these yet ? They've kinda been around a little while but this is my first experience with the latest version of them.

In a nut shell , they will pierce something around 3/4" or better armor steel sheet (and thicker bullet proof glass and the like) yet fragment to nearly 100% in soft tissue.

What that means is should a target behind said steel exist , the bullet will pass thru the steel intact and fully fragment in the target tissue.

Or in contrast , an armor piercing bullet having full stopping power in soft tissue as opposed to blasting thu and thru and hitting un-intended targets in the back ground.

Any thoughts in this technology ? Positive or negative ?

Oh , and yes . . . they most definitely function as designed. Exceptionally ingenious principle.

As soon as YOU works all the bugs out, these are going to be the greatest thing in bullets since the Minie.


...so get to work, slacker

Sha Right.

That's not my end but what I've experienced so far is pretty impressive. Me thinks a few of theses might make it into my CCW for sure.

I must say that it is interesting to know thats there. The only thing I shoot is a 270 and I doubt I need that for deer hunting but, Im sure the guys who have to make the decision to pull the trigger will appreciate the concept.

My cousin was telling me about these at christmas, sound really interesting to me. I really want to try them out

What about clothing or a vest? Couldn't a heavy jacket cause it to fragment? What about a light vest?

What about non-military / personal defense applications?

Say hunting

[Dubstar112]

Oh so true. But would dense brush make it frag? Thats such a technical shot!

I think the problem with dense brush would be knocking it off intended course more than fragmenting

Think thicker then, until you cant prove me wrong in your head

There was a special the history channel, Modern Marvels: Bullets I believe.

They did a 5 minute segment on these things.

All I have to say is WOW.

They show it piercing a steel silhouette, then show it literally disentigrating a piece of meat.

Not going to lie, kinda scary. It looked like someone put a large charge inside of the meat.

Like a tree

Im gonna need some trajectory charts of one hitting a tree and passing through. Im gonna start practicing now.

These bullets will never work as good at deer hunting as salt lick off the back porch.

In simplest terms , the tip is a material matrix that reacts differently to temperature conditions.

Below certain temps , like that of cold steel , the tip contracts at impact and lowers friction coefficient to allow it to stay solid at impact and 'slip' thru the metal. At warmer temps (human) it shifts the opposite direction and ramps the friction coefficient which causes the tip to turn to near powder form. From that point , the rest of the bullet is like a mini grenade. It does all this in fractions of a millisecond and with a good deal of reliability and dependability.

Nothing short of amazing that the theory works at all.
