Re: target results
Maybe both rubbers at 360% is overpowering the gun. The 6.75 shaft may not be able to handle all that power.
Retie the band for the rear notch using a longer wishbone (which will decrease the stretch ratio) and see if that changes anything. If it doesn’t change anything retie the other band as well (effectively reducing the stretch % on both bands) Also, are you gripping the gun firmly when you shoot?

Re: target results
are you gripping the gun firmly when you shoot? yes and its very low recoil as the gun is well ballast ,I ll try tomorrow morning ,I remove the thick wishbone and replace the 2 band with single 16 mm 330 % ,visibility here is very low I can't see more than 3m in murky sea .
