Re: Focal Plans
Where the reticle is in relationship to the magnification...
With Front Focal Plane scopes the reticle works properly on all powers, with Second Focal Plane scopes the reticle only works accurately on one power, usually max power but sometimes on others.
Front Focal Plane scopes, the reticle changes in size in relationship to magnification on Second Focal Plane scopes the reticle stays the same size regardless of power.
