Hey,
my crosman1000 sounds like a frog!
took the stock apart, found one thing- the Roller on the cocking lever has a flat spot worn down, at about 500 pellets,
I cut a peace of 12ga allm 1" x 5 3/4 long & Drilmaled out a slot for it now the roller rides smooth on tha metal,With moly 60, then the wood stock.
Is there a site that shows how to take apart a 1000? tune up your self, without getting to deep!
Ron
