Excellent shooting Neil.
Defiants btw are a totally different pellet. Only 7.5 grain and can run up to about 840fps. Air Ammo (Paul) supplies them as well as JSB
Webley Mosquito is made by JSB exclusively for Webley in the UK.
A similar JSB branded pellet JSB Exact Express also 7.9 grain is available outside of UK.
I have both and cannot tell them apart.
Craig uses Mozzies in his Zenith at about 810 fps
see you Sunday
