Thanks guys.
Manthing, yep, I love the 97 and it certainly bowls the rabbits over with a satisfying (for me, not the bunny
) thwock. It's 4 years old but like new as it was hardly used until I got my new shoots and it has had approximately 500 pellets through it, I bought a tin of Eley Wasps when I got the gun new and I have just bought a second tin of wasps. If I was to guesstimate, I'd say it has fired 450 shots. It is dieseling on every shot at the moment though. I'm thinking it's probably the internal lubrication from new burning off but I did wipe the inside of the breech last week with my oil rag as it got wet in the bad weather we've been having.
