Mr Dink, I have done a load of tests on this rifle with various pellets. Sizing the pellets doesn't seem to do anything for consistency, compared to the 7.9s, especially the ones that were badged Mosquito Express. I always used them as a control pellet to see how the new variant or alternative performed. If I can find some scans I'll post them up.
It probably is the CZ barrel Rich, same as my EV2 Mk1 which was one of the first released in February 2004. Mine has the CZ barrel and like yours prefers the Webley Mosquito Express which I still have just one sleeve left now!
From memory it was some time after when they changed the barrel, the Mk 2's I think?
