Zeroing the scope

Yup. Show us the windage turret and what you see.

1 CLICK = 1/4 MOA.

Well, this sounds familiar! Yes, adjustable turret scopes tell you how and how much to move your bullet impact on the target. The Windage knob will adjust the bullet right or left. The Elevation knob on top will move it up and down.

Start by firing a group of three or four rounds at the 100 yard target.

Check the group.

I’d say we want to bring the center of that group down three inches and left three inches. So, if 1 click is a quarter of an inch, 4 clicks is an inch and 12 clicks is 3 inches. Dial the elevation down 12 and the windage left 12. Shoot three or four more rounds. Voila!

Not bad. I’d move windage right 3 or 4 clicks and see if the center of the group is dead on. Don’t be afraid to expend some ammo to get it right where you want it.
Once zeroed, you need to be able to return to this setting routinely. Scopes have various ways to do this.
This zero point is the basis for everything you will do henceforth.
