I just received the tungsten rods!
Each weighing 20g
EDIT : impossible to grind!

So what... it's a hole punch
... when can we expect the first test?

Excellent 
it would be cool to see if the arrow sabot works too if you have time

Are you using tungsten rods, or tungsten carbide? The former should grind on a normal wheel, and the latter, of course, requires a diamond wheel if you're trying to take off large amounts of material as would be required to make a point.

A couple of metres should be enough for the sabots to separate cleanly.Petitlu wrote:How far I have to set the target?

Tungsten is a dense, high melting metal used for radiation shielding, very high temperature applications (mainly electrodes), and as an alloying element. Tungsten carbide is a ceramic (although what you actually buy is called a "cermet", a portmanteau of "ceramic" and "metal", due to it being tungsten carbide powder bonded together with a metallic filler) used mostly for tooling, and for wear resistance in general due to its high hardness.
Both have seen use as projectile materials due to their high densities, although tungsten is more dense than either of its carbides.

The SP-4 silent cartridgefires a simple flat headed steel cylinder:Petitlu wrote:even the flat head, enter to the steel!
At ten grams and firing at a low (by high mix hybrid standards) 200 metres per second, it claims complete penetration of one inch of pine board or, or a standard army steel helmet.
You're going to be firing a smaller diameter, harder and much denser projectile, probably at much higher velocity. I say prospects are good

Oh come on, add a little bit of distance, there's not point in making fins other wise
of course you wouldn't want to miss the target, but unless it's really small that shouldn't be too much of a problem with a fixed canon.
The first shot I tried with a 4mm tungsten rod in my spring loaded ball valve air rifle at fairly low pressure made it though a 3.5" pine block.

Seems about right in my experience, I've definitely made it though 1" of pine with my pneumatics and full bore projectiles.At ten grams and firing at a low (by high mix hybrid standards) 200 metres per second, it claims complete penetration of one inch of pine board or
