At the bottom of your pic that's covered up should say these figures are only valid at the highest magnification setting or something to that effect. You'd have to convert them if using less magnification than 6x.
yep, but I would only use straight power or fixed but not that many offered. If it was first focal plane , wouldn't make any difference. I do know that
the small vertical line at bottom, by adding 12 Moa placing tip on target got me to 500.
