...Or, stick the ram in the lathe, drill and tap a hole in the pocket in the rear plug and make a tool to open the valve, ala Benji bleed tool....Sometimes education can be painful.
May need a 16- 18 gr pellet to calm it down , defiantly Hatsan 125 power if you crony is reading right, how many thicknesses of 3/4 " plywood will it go through
I usually get about 750 fps in my 22 Striker/Edge rifles using the CPHP. It seems like yours is shooting a little low at 650 fps. It may just be the NP1 in the Striker action or it could be there is now some piston seal damage from the over pressurized Vortex?Regardless, glad you got it to work. Sounds like it was easy for you!
Pull the breech seal, get some unwaxed dental floss, put a couple layers in the cutout for the seal, then reinstall the seal. May or may not help some until you get the new breech seals but it can't hurt to try.
The bent pin and 2 handed difficult cocking means that Vortex was filled way over pressure. If your pressure gauge read only 100 bar then I suspect the gauge is bad. Maybe it filled to 200bar!? Until you can find and fix the problem please be careful filling any pressure vessel. There is not a lot of volume/energy stored in a Vortex but it can still be very dangerous. If you are double-pressure filling anything larger it could become a lethal bomb.
