OK
just got my furter sight,
another billy lid question.
once it is on the rifle and have it zeroed correctly, is there any method or adjustment to the sight so it can be re set to its corresponding markings?
Is the elevation adjustments calibrated for the elevation changes of the standard GP11 round?
If I have it zeroed at 100 and the elevation reads 400 for instance sake can I get it back to 100 on the knob without changeing the elevation? i.e. like loosening the knobs and resetting?
Same for the windage, I know that it will chnage with different conditions but If I have it zeroed can I make the indications on the knob read zero?

Please be patient with me, I have had a lot of experience with Parker hale sights, central, mues etc etc on other rifles but not one like this furter,
cheers and thanks
