[QUOTE]"First focal plane 'European' scopes cannot change point of impact when changing magnification because the reticle does not move.
First plane scopes with rangefinding type reticles may be used at any power.
Second focal plane scopes or 'American' scopes are smaller and lighter and can have point of impact change magnification, and many of them, especially less expensive one's certainly do. Second plane scopes with rangefinding type reticles are designed to be used at one power only. Second plane scopes also have a smaller appearing reticle on the target at high power than low power, which is extremely important for precise shot placement."[QUOTE]
