I actually haven't fired it yet after getting it back together but I probably should as I did make one kinda major tweak while it was still apart.Mine is a Vortex....and I have a hand pump and Hatsan fill probe, soooo....I jacked the pressure in the ram before I put it back together. Standard pressure is 125 at least according to Hatsan....my pump gauge read 150 when I stopped...it will either blow the seals or I'll have a beast of a 95 .25 caliber.I'll post when I get a chance to shoot and chrony it.
