I will play with current set-up some more, also want to experiment with different muzzle velocity and its influence. That’s another can of worms.
The mount I have now is a one-piece quick-detach, supposed to be quite sturdy and overkill for pcp. But I can not turn the rings 180:

I did some basic cleaning and re-install of rail, followed by my Tall Target test: After zeroed at 57 yard, I clicked up 45MOA, the new group is 26.75″ high, and 0.75″ to the right. Yes to the right, instead of the previous error to the left. So I rotated scope CCW, till poi lands on vertical line. However the…Read more

I think it correlates to your earlier suggestion of “shooting a square” to see if the 4 poi s can create a square vs diamond.
Lately I have not yet found a windless day to test it, but based on what I just saw, I am almost certain the scope needs to be rotated in the ring.

@pippo, can’t turn the barrel because the port location is fixed.
@Greg, I see you painstakingly measured out the cant angle of the scope vs barrel, and shim it. Wouldn’t you achieve same effect by adjusting windage turret?
@kris, interesting thinking about the…Read more

During the research of buying a .25pcp, forum reviews and Evgeny’s product and service convinced me to get a Vulcan.

I couldn’t agree more! This case is a testament.

The new air tank is now in the gun and I put about 100 pellets through it. Everything worked well and life is good. Now only if I could get my V.25 quieter :winkn: …..

During the past week while I was waiting for the air tank replacement, I have been shooting my very quiet .22 HW100…Read more

Today the June 12th, I just received a brand new air tank from Airgun Technology via Fedex. I am almost certain he sent out the replacement part same day receiving my email.
Through this exercise I have learnt a lot about my Vulcan.25, and the people who…Read more

Let’s hope the shipping cost is not high…

Talked to Tony, he is several steps ahead of me, already sent out inquiries to Airgun Technology before I reached him. I was advised to wait for a response. Thanks Tony!

I have hard time to understand the tilting of reg body under pressure dynamic, it holds square OK for the first fill, but not after it drain down pressure, then start tilting during the re-fill . My worry was the leak, but now my biggest concern is the tube maybe no longer round and loose its structural integrity: there is…Read more

Air tube was charged last night and holding pressure at 240 Bar 12 hours. I was happy to see no leaks.
Shot about 40 some pellets, pressure dropped to about 110bars, everything appears fine. Until I need to fill the air again.
Turn on my tank and tried to slowly fill the tube, the vent hole…Read more

Although the O’rings look like still in good shape, I replaced them anyway.

There is something strange about the position of the regulator, when i took off the valve and look inside, saw the regulator was not sitting exactly straight in the middle of the tube, it is…Read more

I did talk to Tony and he is cool about I servicing the O’rings. I plan to change them all while have the system open.
This forum is great, full of resources and help, after reading some helpful posts, I also plan to drop reg pressure and reduce the MV to about 880fps with 25gr JSBs.

I am going to do the same to see if it would fix my issue.

I am having a similar issue with my Vulcan .25 Gen4.
It started several weeks ago when I was filling the gun, when the fill pressure reaches 200bars or higher, the air start to leak out quickly through a tiny vent hole about two-three inches from breech. There are two holes, the air is coming out from the one closer to the…Read more
