Just got back to the club today after trying Webley Mosquitos .22
Quite impressive to be honest, some very good groups and the poi was 1" above the Wehirauch Field & Target Specials. The difference is weight is 0.4 grains (Mosquitos 14.3grains and Wehirauch F&T Special 14.7grains). I haven't tested the pellets out further than 25m as that is the limit of our indoor range but the target and chrono figures were quite impressive. All shots cleared through a hole around half the size of a 5p coin.
The chrono figures are as follows:
601, 601, 602, 598, 596, 602, 602, 597, 599, 5
