Thread: Scope levels - do they work?

Yes, it’s a ratio i.e. distance the scope is mounted above the bore (the rifles bore is the pivot point just like a see-saw) V's the amount the bullet has dropped for the given range your target is at.

i.e.

Scope height above bore = 1.5''
Drop at 1000y = 230''

Therefore if your scope was 1mm off perfect alignment to the right, the cant would cause the following error to the left

[Ratio (230''/1.5'')] x1mm off centre (to the right) = Impact will be 153'' left of your aiming point

That in anyone’s language is a big miss!
