I designed a 3D cradle to secure my air tank to my shooting bench. It's raining so I got creative, great accomplishment for someone who...

I designed a cradle to keep my air tank from rolling around on my shooting bench, it attaches with a 8x1" panhead screw. I'm new at...

Been shooting off a folding table on my back deck with occasional clipping on the top rail when I don’t raise the bipod high enough. I...

Glad you got it figured out. Sounds like you are in an excellent spot. I don’t personally ever tune with a reg pressure high above...

Told.ya! Excellent

I had another issue with the chrony and had to start over on the tune. I started with a regulator pressure of 85bar (I thought I was at...

Never heard of the “knee”, as most of the YouTube tuning videos suggest finding the plateau and that’s your balance between pressure and...

The regulator pressure is the plenum pressure 900 with 25.39 is the STARTING point for that gun. You should be way lower in the hammer...

I guess I need to back off the hammer, set regulator to 110 or 120bar then adjust the the hammer to get 900fps, hopefully not having a...

Mine actually has an exposed wheel on the left side that adjusts the hex head that you’re showing.

I’m probably about 85 clicks in on the hammer spring at 100bar. If going up on plenum pressure would require a heavier hammer spring...

Correct, when you increase pressure, you increase hammer SLOWLY. go up 10 bar, click up 1 or 2, shoot 3 shots... see where velocity...

It’s a .25 with a 600mm barrel shooting JSB 25.39gr. My velocity dropped when I increased pressure above 100bar with same hammer...

No. Max pressure and max spring doesn’t equal max fps. You’re overpowering your hammer spring. That’s why your velocity went up when...

common mistake your hammer+spring can not generate enough power to open or keep the valve open long enough with that high plenum...
