What is it?

I'll try to post a pic later if need be. I have a bullit from a berm I was mining. While I was cracking full encsaed bullit I came across this. The outside is a sorta of silver or grey color, very smooth. When I tried to crack it,it split in two. The inside is a kind of copper color. Where it broke the inside is very porous and rough. Never seen anything like it before.

I found a few like that too mining the berms. I think i still have one on the workbench. Not sure what it is?

Sounds like a frangible round.

If it's a frangible then why didn't it frang when it hit the burm????? [smilie=1: :veryconfu













Maybe a winchester silver tip??? [smilie=s:

Dirt was soft enough not to shatter it. Many are tin and/or copper powder compressed
and heated to partially stick. It will shatter on a metal plate into dust, not causing injury
in close in training when shooting on steel reactive targets.

I think some of those frangible bullets are zinc. Can anyone verify that?

Here is what I found out about Frangible rounds...
I used the M22 as a reference. It is a .30 caliber Ball ammo.
It is marked with a green tip and a white strip behind that.
The function of the bullet is disintegrate upon striking a hard or armored target, leaving a pencil-like mark to indicate a hit during gunnery practice.

Now, according to the info I have, it shows the composition of the frangible round to be Bakelite BM17073.

Don't know if this helps. How big you think the bullet was before it was shot? I have pretty much all the reference material on the military's ballistic data. I just pick the 30 cal as it is a very common round to be found.
