Hi all
Recent got a combro from BBF , thanks
Checked power on the rifle this evening and was shocked at how much it had dropped. I had been living in blissful ignorance
It was 21.4 fpe with 18.13 gr jsb jumbo heavy pellets at 729fps.
Any ideas on what I need to do to restore the power?
All help greatly appreciated
?

3-4 years old. I think it might need it's seals done.

It could be a combination of seals, tired hammer spring and in need of a hammer rail clean.
Get yourself a seal kit from Julian and give it a once over. Whilst you have it stripped you could nip up the grub screw on the adjuster as this will stop the knob moving power too easily.

Thanks poguemahone
The firing valve? Is it easy to change?

Anyone know the most straight forward way to get to the hammer? I've never opened up an air rifle before

Thanks BBF
Im guessing that part where he uses the drill is to do with the anti tamper that we hear about?
