Totally new to tuning and FAC airguns it’s my first one , I received my fx king 600mm and its at 125bar macro23 micro 2.5 plus 4 clicks it’s firing h&n hp2 27gr at 960fps , am I in the right area it should be running at . I need some good weather to really play with it but at moment the weather isn’t giving me the chance where I live in uk ,
