How to Use a Second Focal Plane Scope (SFP Scope) for Maximum Accuracy

How to Use a Second Focal Plane Scope?

A second focal plane scope, or FFP scope, is a type of riflescope that has the reticle located in the second focal plane (SFP). This means that the reticle’s size and position remain constant regardless of the magnification setting. This can be an advantage for long-range shooting, as it allows the shooter to make accurate adjustments to the scope’s magnification without having to worry about the reticle changing size.

However, FFP scopes can also be more difficult to use than first focal plane scopes (FFP) because the reticle’s relationship to the target changes as the magnification is adjusted. This can make it difficult to estimate range and make accurate shots.

In this article, we will discuss the pros and cons of FFP scopes, and we will provide some tips on how to use them effectively. We will also discuss the difference between FFP and FFP scopes, and we will help you decide which type of scope is right for you.
