Hi Rockman,
I have built my whisper on a cz fox action.
It shoots quite well up to 200m.
I have actually done most of my "kills" near Timaru actually.
3 rabbits(arround 130m, a hare at 165m and a magpieat 100m).
That is with sub loads.
I shot a fallow and a red with 125gr bt supersonic.(North Island).
