[Thanks I've read the uk version of the manual at least, can't see anything in the troubleshooting other than running a rag through for cleaning. Have to say it's disappointing compared to my 586 which seems more solidly constructed. I'll see what the shop says when I return it.

The manual shows you how to clean the barrel.
It has to be done from the muzzle end.

500 pellets is a lot through one of these in such a short time.[/QUOTE]
