The mighty Tornado can be made to shoot decently.

There is a .177 model, FEG (The Hungarian manufacturer) made them for Umarex and Grotthaus on the continent. But being British, Relum imported .22 (which as SMK continue to illustrate seems to be considered the British calibre!). So, you might find a .177 for sale here, but I have only ever come across one of them (ad that was a Supertornado) and that one I bought!
