I was bored. So I took a copper tubing cutter to an API bullet.

pieces

Then I lit a match to the paper the incendiary composition was on.

Tomorrow I'm taking the penetrator to where I work to do a chemical analysis.
The thing is so hard that when I locked it in a pair of vice-grip locking pliers,
they didn't even leave a tiny scratch on the shiny part of the penetrator.

I'm amazed that these can be so hard, without being so brittle they shatter
on impact. Considering how many photos I've seen with them sticking out
of steel plate, they obviously don't shatter.

Too bad I don't have any Rafoss rounds to take apart.

I'm assuming that is a .50 cal round?

cool stuff... I would have though that the incendiary compound would have burned slower... shows what I know.

Yep. Sorry I didn't mention that in the original post.

you want to do that to a raufoss round?

you sir are a far braver man than I

Penetrator is hardened tool steel. Quite tough.

Yea, but jeesh. We see steel samples every day.
Too hard, it shatters like glass. This is a pretty amazing alloy.
Too bad my screwdrivers and wrenches aren't made out of it.

Did you move the camera cause you were shocked or did it have some kick to it?

Either way that is some powerful stuff.

Seriously, great job. Thanks for posting.

Most .50 API rounds have a 'Tungsten' penetrator.

Startled I bet. Always use a tripod!

Hey my watch is made of tungsten

Only M903. Tungsten technology lacked toughness until about 20 years ago. Tungsten itself is only denser than tool steel. Tungsten carbide is very brittle.

And wrenches ARE made of it. High quality thin-wall sockets require such hardness and toughness.

Yea, it actually made me jump.

I'm fairly experienced with pyrotechnic compositions, and knowing what
this powder was designed for, I expected it to burn much slower unconfined.
Large metal particles burn longer, and give it more opportunity to ignite
fuel vapors in the area of the target. But those composition barely burn
unconfined.

That, and the fact that the burning paper looked like it was almost going out,
I was on the verge of bending down to light another match.

Then Woosh! It didn't have any kick, but it was a surprise.

Thanks for doing that, The_Reaper.
