Airgun Technologies Uragan 3 compact .22 - adjustment

I have set up my uragan 3 compact to 160 atm. I am using jsb knocaut 1.645 gr with a speed of 892 fps. From refueling to 280 atm, I get 2 full drums with excellent accuracy per 100 meters. The farthest crow was mined at 191 meters
Nice to get this information from you. Thanks
Does your barrel also like .217?
This is what my U3 looks like.

JaceSpace Thank you for the hint.
So the U3 is built differently than the U2 and it is a classic valve that has a spring that closes it.
He is quite picky about adjusting the hammer spring and it must be done quite precisely. When it is loosely screwed in, the gun is unstable. But today I achieved a satisfactory result. I have 890fps on jsb monster light. That's about 50 joules and about 50 shots.
I will continue to experiment to get the best results.
At the moment, the regulator is set to about 130bar

I have also uragan 3 compact .22.
Need try get it shoot Jsb hades 15.89gr for about 870 fps.
So i can get it more silent.

What was that regulator factory setting?

Jsb jumbo monster light .22 20.83 gr so they are little heavier.

The factory had about 105.. solid silence is a challenge for this short barrel. I have a great moderator and he still barks
 

Thanks for that information.
Surprising low regulator setting for factory, but still shoot so fast.

Now it shoot 847 fps those hades and it is quite silent.
Huma-Air MOD40 Avalanche moderator and one extra modul
chamber + felt.
It is only 55mm longer then stock.

I checked mine again because I rarely use it and it actually makes a difference, but with the adaptor it's 180mm more...
