    if you are sure there is no leak, have you ruled out transfer loss due to heat while filling.

    When you fill, even relatively slowly this generates heat, and a false high pressure is seen at the gague and the guns display which settles/ reduces when the temperature equalises.

    My MK4 was leaking from firing valve. Put balloon on end of barrel and you will see if there is problem - balloon will be filled.
