Re: I think I am looking for a new scope

When the reticle is accurate and you see your shot and you need to make a correction, you use the reticle to measure the correction needed and just make the correction with the turrets. No calculations are required.
It used to be that you had a mil dot scope with moa dials. If the impact occured 1/2 mil right, you had to take 1/2 mil multiplied by 3.6 and then dial your correction which in this case would be 1.75 moa. With a mil/mil scope, you dial 0.5 mils left and shoot again.

If you are shooting at a target that is located at 731 yards and you take a shot with a 5-25 power FFP scope and mirage is bad so, you have the power adjusted to 16.3x and you see your impact is 0.7 mils left, guess how much right windage you put on your second shot. Thats correct, 0.7 mils.
Now lets take the same senario with your 5.5-22 power SFP. Mirage is still bad so, you have to crank your power ring down to 16.3x to get a good sight picture. You take your shot and see the impact is 0.7 mils left. What is the correction for your second shot??? Your reticle is accurate at 22x and 11x (twice the correction). I don't know about you but, I don't want to have to pull out a calculator and start running the nimbers to get my correction. I know that the conditions will change before I can get the shot off.
FFP scopes give you a measuring device (your reticle) that is accurate at any power. The reticle does however become more difficult to see when the power is turned down.
SFP scope give you a constant sized reticle that is only accurate at it's highest magnification. This will become an issue when mirage will not allow you to run the scope at it's max power.
If all you will ever do with the rifle / scope combo is shoot paper at fixed distances, then a SFP scope will work just fine. If however you will be shooting at targets and making corrections based on a first shot in a wide variety of conditions, the FFP will be more versitile.
