Question

i need to know

how to calibrate with the screws

Answer 1

By calibrate, I assume you mean zero.

Set up a target, aim at the bulls-eye and shoot 3-5 shots from a solid rest (a gun vice would be ideal, if you don't have one, prone position may be the best set up. You don't want the gun to move when it is fired.)

If your shots don't make a small group, then the target is out of range, move it closer and try again.

If your targets make a small group, but it is not on the bulls-eye, you need to adjust your scope. There are usually screws or knobs on the top and side for adjustment.

Continue shooting and adjusting until you get a small group right in the bulls-eye. Note that you may need more than one target.
