ok, I'm sort of sorted.
The scope is shooting accurately enough.
Part of the problem was me shooting in the wind. I didnt even stop to think, because the deck I shoot from is nice and sheltered, and the targets are out in the paddock in the full force of the string somewhat gusty breeze.
I think the wind was also a factor in the excessive drop between 25-50 yards - the path between my firing possie and the 25 yard target is also relatively sheltered by comparison.
What a dick
Its calm now, and I just shot the same accuracy as I did previously with my other Tasco (3-9x30) (overlapping holes @ 25, half inch group at 50 yards)
However, the issues with the turret wound up to the max still remain.
might see what the local gunsmith has to say about it ...
I think Zimmer's advice re the rings may be the next port of call in solving this.
cheers for the help guys
