Thanks Frank I've had a bit of play with it this afternoon and cant get the Vertical axis anywhere near the line of fire. The L and R adjuster on the side is fully wound out to the Right and a little knurled as if someone has tried forcing it further. Its not a major problem it just means a visit back to the dealer who I know for a fact will sort it out, it was just a bit disappointing today not being able to do some groupings. Thanks again for the advice.
