Depressurizing Hatsan 125 Gas Piston

Hello all!
Long story short, my Hatsan 125 was outputting around 19 FPE, which is way less than the 33 FPE advertised on Hastan's web site. I decided to follow a video tutorial where you could increase the power by pumping air into the piston (YouTube video name: Hatsan vortex gas ram part 2). The problem was that I ended up adding more air than I should (more than 150 bar). I know that the piston has a hole in the other side with a screw where you can bleed the air, but
here is my problem
: such screw is not turning anywhere! And to top it off, the screw is getting stripped. How can I depressurize this gun!?
Thank you!

You might PM member MikeyB. I believe he has depressurized a Hatsan gas ram.

Hatsan screws are made from fairly soft steel and the heads will smear or strip if you try to use a tool that is not a PERFECT fit. I take oversized tools and custom grind them to fit my Hatsan fasteners. Then I store those tools in my "Hatsan ONLY" tool box. Have not stripped out a Hatsan fastener head when using these tools.
I degassed a Vortex that had NO bleed screw. It was a destructive method not without some risk. I was able to repair my Vortex after that, but decided to retrofit the rifle with a coil spring. I have the rifle shooting just fine with the coil spring and have no plan to put that Vortex back into service.
If your Vortex HAS the bleed screw, STOP and make a proper fitting tool now before you cause too much damage. If you have already stripped out the screw head, I don't have any constructive suggestions at this time.
Sorry :-(
