What were 'metal piercing bullets' made from before? My 30-06 Springfield
(military model) came with some clips full of MPBs.

I know that some were made from a high molybdenum steel with surface hardened
tips. There are different ways of doing it, the above is 1960s era technology.

The bullet needs to be dense enough to carry a lot of energy into the target
surface, and enough harder to not get distorted (so that the energy of impact
stays in a small area) and yet surface hardening also makes metal brittle, so if
you overdo that part, the bullet just shatters. Depleted uranium is much simpler
(once you figure out how to make it in the first place) but as Martin said, the
dust & debris around the target are not healthy.

It doesn't do much for our "good guy" image to leave low-level radioactive
debris all around a country we've liberated. Future generations will not toss
flowers in our path for elevating their cancer rate! Just my humble opinon.... I
wonder if the US has really stopped using depleted uranium, or if they've found
something almost as good?

BTW did you see the clips of Carolina beating UConn?

Just about any really dense metal will do for this type of technology, I've seen rounds
made with hardened copper that work quite well. The big problem is finding something that
is really dense that has sufficient tensile strength to withstand the acceleration of being
fired from the weapon and at the same time is not expensive. DU filled these requirements
nicely, it's a waste product and thus cheap, as an added boon this was a great way of disposing
of several thousands of tons of unwanted radioactive waste. I believe I read that making
this type of kinetic round with copper is actually more expensive than DU.

DU is NOT radioactive waste, dumbass. DU is the byproduct of removing
the radioactive isotopes from natural uranium. It's called "depleted
uranium" because the valuable radioactive material has been removed.

That's why I think you have a depleted cranium.


;-P

That would be assuming he had a source to deplete! :-)

You may be the thickest individual to ever post on this news group. co some

Why would you say that?

What is "co some research"?

Because you cleary do not know the mechanism by which depleted uranium is obtained.

So sorry, co=do, that shouldn't have been too difficult to decipher,
I'm suprised at you.

Now go see if you can find out how a US light water reactor works.

Natural uranium is distilled in a centrifuge. The 235 isotope is
lighter than the 238 isotope and is skimmed off.

Did you forget that I am an engineer?

I know how. What's your problem?
