problem with prostaff

[im12agen]

Just collected my new Ruger 10/22 and some Winchester subs as well as a box of Remington subs. The first thing I did was to dismantle the stock to fit the sling studs and pull a bore snake through. Next I fitted the weaver style scope base adapter with the four screws supplied, I have checked again for tightness. I then fitted the Nikon scope previously used on a CZ 17 HMR and up to to yesterday an Air Arms 510 always spot on. Went to my permission with a large target and set up my tripod at 25 meters but could not register anything on target and kept adjusting the turret up. After 20 shots it was turned up as far as it would go and still shooting 1 meter below. Since then I have removed the scope and changed the rings around removed and replaced the stock. Any advice would be received with gratitude.Alan.

Make sure that the rail is fitted correctly-visually inspect the mounts to make sure they are identical-remount the scope (make sure its not touching anything but the mounts) and then centralise the scopes elevation by counting the amount of clicks from one end of the adjustment to the other-set the adjuster mid way.(make sure that the scope is the right way up i.e. the top turret says elevation or U on the dial. If the gun shoots way high or low over 25 metres then take it back-you have a barrel alignment issue which is not uncommon on the 10/22. BTW junk that ammo and use Eley or RWS subs.Hope this helps.
