Nice one, Pete.
How's your little chap doing?
Boingy things I must get around to doing include whipping that plastic fantastic little Gamo to bits and de-boing it. See if a tighter fitting guide can be made to fit or if a suitable spring with smaller ID can be sourced. And the screw-in end block HW50 that I managed to get recently felt in need of a fettle and slip a Rekord trigger in there.
One day I WILL get the time!
