If your scope centre is at a height of 1.75 inchs to centre of yr barrel bore.And yr scope vertical line is 8 degrees off plumb which is really easy to see.The length of the circumference line on a circle of a radius of 1.75inchs between plumb and yr 8 degrees is only about 1/4 of a inch.
So if you zeroed at a 100yds,your bullet at 200yds will only be a 1/4 of a inch to left or right.So scopes that are 1 or 2 degrees off plumb to bore you never notice out to 500yds.
