How do we avoid the parallax error?

Place your eye at the level of the appropriate measurement marking when measuring the level of a liquid in a graduated cylinder. Read the lower part of the curved surface of the liquid — the meniscus — to gain an accurate measurement and avoid parallax errors. Ask other people to take measurements.

Do I need a scope with parallax adjustment?

Parallax at Varying Distances You will need to adjust the parallax when you are shooting at varying distances, just like the scope. While it may sound cumbersome and slow to adjust your scope’s parallax setting for every range, it’s something that you only have to do once when you start shooting at that distance.

Which is bigger 1 inch or 30mm?

A 1 inch rifle scope has a main tube diameter of 1 inch, or 25.4mm. A 30mm scope’s main tube is 30mm thick, obviously. This was originally due to differences in manufacturing methods and the fact that European manufacturers used the metric system. However, a 30mm scope does offer two advantages over one inch scopes.

Is 30mm the same as 1 in?

If the 30mm scope has a greater range of adjustment, it simply means that internally the lenses are the same size as the 1 inch scope. It will not perform any better than the latter scope, all else being equal.

Are BDC reticles caliber specific?
