Modern scopes adjust for point-of-impact byturning two knobs, one on top of the scope for elevation,the other on the side for windage. The erector tube usuallycontains several lenses and, as it is adjusted from side-to-sidewithin the scope, affects the firearm's point ofimpact.

Also question is, when adjusting a rifle scope Is up down?

What does 2 MOA on a scope mean?

It means the adjustments on the scope arecalibrated in (usually) some fraction of a 'minute of angle'. At100 yards a minute of angle is approx. 1 inch. Each 'click' on thescope's turret will be most likely either 1/4 MOA or1/2 MOA. That said, MOA is an Americanthing.

What is holdover in shooting?

Hold over normally refers to aiming above yourtarget because the bullet is falling as it travels. The simple wayto think is the farther the bullet goes the lower it will hit onthe target. Saying there is no holdover at 300 means thatthe weapon is zeroed at 300 yards or shoots "flat" enough that itdoesn't matter.
