Sorry , being rude ! thanks for the reply’s

Plenty of air , place pellets in as far as poss ! It’s as if something is in breech ? I’ve used this gun for a couple of years and shot hundreds of pigeons etc . Always cleaned when needed to keep accurate ! Looks like a complete strip and remove the breech and see what’s in ?

Tried putting a pellet in (177) and the bolt needed more force than normal to close ,tried firing and no pellet ! Put my brass cleaning rod down and eventually the pellet came out mangled ! Put another in same result , cleaned with brass brush and pull through tried again same result ! Anyone any id...

Thanks for that guys
