Problem solved. Different scopes behave different on a particular air rifle.
Had some business in the old Abra market last week. Out of interest walked up to the old Captain store ( dealer for Gamo / BSA ) to check if he had any Tasco scopes.
He had some nice Gamo and BSA Air rifle scopes. Picked up this GAMO 2-7 x 32 mm AO, with parallax adjustment ring on objective, this was very similar to the Bushnell SPortsman I have on the .177 Diana 68.
Put it on and tried it today. First shot hit the 10 ring of the standard Gamo 10 cm x 10 cm target. 25 notches up, it hit the 5 ring, i.e. still 1 1/2 inch low. There was room, 20 notches up again and to my delight the Gamp Pro Magnum struck 1/2 inch high. Adjusted back by 10 notches low and then tried for groups. The HW shot perfect groups at 10 m. One pellet into the other. Less than 1/4 inch centre to centre at that distance.
Perfect for longer distance shots now ! Problem solved.
