Thank You, yes I am in CA, USA. There is no power restrictions for airguns in the States. I know the TX200MK3 has 17.5 fpe for the .22 cal in FAC version, and I haven't been able to find out much information on the HW97K, all I know is that the UK version is only 12 fpe. I would like to know the muzzle energy for the FAC version of the HW97K.
