22lr has probably shot more fox's than any other calibre,the only reason for this is that there are so many 22lr's in cerculation they will also have wounded the most fox's aswell...rim fires arnt any use what so ever as a dedicated fox round..hmr will just about do the job but its like knocking a wall down with a toffee hammer....there's so many world class shooters on thl that will claim extreme long range shots on the lamp with what ever calibre..the reality is that even with a centre fire the average will be little over 150 yards if that...if your getting into shooting get a rim fire,leav
