FFP & SFP scopes?
I have read that variable second focal plane (SFP) scopes have to be adjusted to a certain magnification to range a target correctly. Also the thickness of the reticule stays the same thickness at all magnifications.

The variable first focal plane (FFP) scopes can range at all magnifications, but the reticule gets thicker as the magnification increases as the power increases. If the target increases in size along with the reticule isn't thickness relative to the size of the target so it really doesn't matter.

Am I correct or not in my thinking? Please let me know one way or the other.

Yes, you've got the basics covered.

Think about it in the other direction. In a SFP scope as the magnification increases the relative size of the reticule gets smaller. That can be a good thing at high magnification and long ranges.

If you have a SFP scope and are aiming at a small target that is just covered by the reticule, you can increase the magnification and make the target larger in relation to the reticule. If you have a FFP scope the target will be covered no matter what you set the magnification to.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
