Thanks chaps !
Will look into getting a new o-ring first off, could you advise which one I need and where from or is it a contact Daystate job ??
I haven't got a charging bottle either as of yet as it's at a mates' house and I don't fancy stirrup pumping the 500cc bottle, (my HW 100k is enough !) so once I get it I will fill back into the green and also get some heavy pellets and see how it goes
Also could you please advise what fill level approx I should be aiming for ? I think the gun is set up at 32-35ftlb ME.
Cheers
