suggest go to range and take a white sheet of target paper and just draw a bold line vertical on it and put a paster in the middle, shoot at 25 yards and adj windage zero on mount, first you want to verify that you are in fact in the middle of the windage adj
this is quite simple, take adj and go all way to left count clicks, then go to right and count clicks
mechanical zero is in the middle, put it in the middle and then adj the windage on the mount to match the zero you est by counting the available clicks on scope
move to fifty yards and touch up, you will find that the mount on the A4 can get pretty minute in its adj, and you probably will find that when you move from25 to 50 yards a inch or so will be at fifty when it was not at 25.. tighten the screw on the mount, to move it,
my A4's are all now marked for mechanical zero on scope, with silver paint and a engraved dot on scope adj ring, can go to mechanical zero any time i want to, but i leave mine on zero for 200 yard dope
