Fron of First Focal plane reticle position was a predominant riflescope design in the past. Today, such reticle arrangement can only be found in tactical riflescopes and in a few classical European hunting riflescopes.
The main feature of First focal plane reticles is their subtensions do not change with the magnification change. That means reticle subtensions in such riflescope can be used for distance estimations or bullet drop correction at any magnification setting. This is of paramount importance in tactical scenarios; thus, all real tactical scopes have First focal plane reticle placement.
Usually, the first focal plane riflescope features the clicks matched with reticle subtensions and are named MIL-MIL scopes. Another benefit of the First focal plane riflescope is the point of impact does not change with magnification change.
The majority of new hunting scopes are not produced as First focal plane riflescope; however, these reticles are thick on the highest magnifications and cover more target space than Second focal plane (SFP) reticles. With super-zoom scopes with a zoom ratio of 6 times or more, this feature became even more noticeable, since the First - focal plane reticles in such scopes are thin on low magnifications and thick on high magnifications.
