Have you modelled your hybrid with these different projectiles in HGDT? I'm just curious to see what velocities and muzzle energies HGDT thinks you're getting; even if the results are a bit exaggerated.

Mix30 22g : 1247j 337m/s
Mix40 22g : 1636j 386m/s
Mix40 22g : 1636j 386m/s

Some playing around with the GGDT range tool and a lot of approximations later, I got a maximum range of about 3.5 kilometresPetitlu wrote:Mix40 22g : 1636j 386m/s

I should buy a good chrony ...

Yep - you can get a good one for less than 100 euro.Petitlu wrote:I should buy a good chrony ...
Random sidenote, this fires a projectile not unlike your aluminium tube slugs
and the the translation is right, the tip is from an arrow head...Posted: Sat May 05, 2012 6:07 am
Chrony in the F1 is?
Although this principle, the arrows look like the arrows from a crossbow

yep, here you go: http://cgi.ebay.fr/NEW-SHOOTING-CHRONY- ... 4d00a09306
It's probably cheaper from a local shop.

Nice!
... but the question is, how hard are they...Petitlu wrote:Very sharp!

bah .. ... stainless steel arrowheads are usually hard, we'll see against the profile!

How we know exactly the recommended weight for a ammo?

It depends on what you want to do. Low, medium and high weight projectiles could all be ideal, depending on the application.RJB INDUSTRIES wrote:How we know exactly the recommended weight for a ammo?
Looking forward to itwe'll see against the profile!
that over the speed of sound should do pretty well by virtue of its weight.
