More only pneumatic hammer.
The electronic hammer is almost at the limit.

Is this a PCP with an electric firing mechanism? 

 

[Terryb00]

Holy cow!

That sounded way powerful!

How is the accuracy at that power level?

Barrel length and operating pressure @ valve during shot? Good build.

Not a mechanism. Impulse solenoid like Daystate. Only Russian and more powerful, better. Light.





Special material electromagnet.

120м. 131yd

700mm, Lotar Walter. pressure 4400psi.

I put different barrel , usually length 440mm or 260mm, the speed is less.

700mm - 310-328m\s

440mm - 280-270m\s

350mm - 250-265m\s

260mm - 220 m\s

Remove the barrel and put - 1 minute. very fast. Create a video? 

Sample - barrel 440mm, pressure 300 BAR, - 251m\s , 252, 260, 263, 263, 266, 266, 266, 268,267, 265, 265,264, 260,258. pressure 210 BAR

Bottle 0,35l + 0,048l = total 0,398l

More videos of shooting please.

 

[DEN54]

More videos of shooting please.

It's winter now. I have a new project, a lot of work. There are only old videos, slugs 0.25.

New project full auto - 9мм. I make several orders. Pneumatic hammer, electronic control. Another topic. New topic.

This gun, which we are discussing in my hands there are, I sold out of three years, mass production.

So if I understand this correctly you are using a solenoid to open the charge chamber instead of whatever else is used?

Yes. solenoid, impact. The voltage pulse is 100 volts. Scatters 18mm. Very accurate shot. Minimum time lok. Easy trigger. Sports descent.

Thanks I get it now pretty cool mang.

What are you using for the micro controller 

Arduino?

 

[DEN54]

No Arduino, although it is possible. Not a big deal.
