Fantastic, can't wait to see it in action!

I got 22.34g for a tungsten carbide rod that size, given the standard density of 15.8g/cm³, maybe it has a higher carbon content.

[DYI]

There's also the cobalt content to be considered when you're looking at something like what Petitlu has, which would be a carbide blank intended for being ground into a cutting tool. 15.8g/cm³ is just WC, whereas one would expect the W-C-Co system to have a lower density. There is also, as you mentioned, the issue of variable W:C ratio. These things are never as simple as you'd like them to be

HAHAHAHAHA!

Superb! Hole punch indeed

We need more details, please tell me there's video, and you put a whole bunch of stuff behind the steel to record the spalling!

Interesting "splash" marks around the entry hole... was there target material in front of the steel?

Did the rod remain intact, have you found it at all?

[Petitlu]

hehe!
Video coming soon!
Target: wood / profile / 2mm steel
tungsten has passed through the wood, the profile and a thickness of 2mm.
The rod is probably defragmented!
no trace ...
It was a shot at Mix30

I made a shot with the arrow also ...

cool! you should try shooting the beam from the side, so there are two thicknesses of steel to go through

The rod is probably defragmented!

I would say it's buried somewhere... or in Belgium

You should put enough thickness of wood (or telephone books...) to stop it twenty inches is enough: http://www.theboxotruth.com/docs/bot31_5.htm

Ooooh! did it come out intact, and fly straight?

YES !!

I would say it's buried somewhere.

I'm sure the bulk of it is but tungsten carbide is also pretty brittle, I wouldn't be surprised if bits broke off.

From where PetitLu lives to Belgium is well over half way to where you live, I'd be worried as the mixes get higher


Edit: Oh the video is up. Much nicer recoil there too

I think we need to see a side perspective of the next shots ! And also some fruit should be included

[MrCrowley]

Awesome! I love the mess it made around the hole *ahem*

[Petitlu]

We killed the profile!

It was a shot at Mix30! next time will be at Mix40!

Brilliant!

In spite of the low weight the sabot and fins seems to have a made a mess of the chipboard too

That arrow definitely hit head on! I would have shot at the 2mm steel so you could make comparisons with arrow tests at plate armour, and backed it up with thick wood.

Great stuff, I agree with al-xg that we need closer video (with a suitably protected camera of course )

"That arrow definitely hit head on! I would have shot at the 2mm steel so you could make comparisons with arrow tests at plate armour, and backed it up with thick wood. "

I wanted pierced profile!
The arrow was shattered on the floor, small little cuts.

I like the hole made of tungsten, an effect of "heat sabot"

I think for the camera, we must protect it or a big zoom

[al-xg]

Just don't use a 7D maybe

[jackssmirkingrevenge]

From plain steel that was a bit optimistic

hehe it does look a bit like a HEAT round hit - though if you look at kinetic hits on steel plate they look similar:

I think for the camera, we must protect it or a big zoom

A sheet of reasonably thick (5 or 10mm) polycarbonate sheet is good enough to protect from any ricochets and shrapnel.
