How many shots have you put through it so far? Springers need some break-in before they start to settle down.
How are you supporting it? Same way every time? Letting it move a little with the shot cycle?
My old Stoeger X20 in .177 started out all over the place, like your ATAC. By the time I sold it, after thousands of pellets had been sent through it, It would shoot 1.5″ (38 mm) 5-shot groups at 40 yards, (36.6 m) if I did my part.
Also, what pellets are you using? Hopefully something decent.
