I have a few higher power, 4-16 and 6-24X FFP scopes and like them very much. Most are mounted on my air rifles & since they all have MOA reticles with a lot of stadia wires, they give a multitude of fixed aiming points or longer range shooting.
I have found this on-line ballistics calculator to be quite accurate to 1000yards with a couple of my rifles. Plug and play, putting in your bullet BC and velocity, this chart gives the MOA correction all the way to 1000 yards - or more.
I think it can also be set up for meters.
