    I have a Ziess conquest 6.5 x 20 z-1000 redical and have on the bench zeroed in at 500 yards. Does the point of impact change on this scope with the power setting??

    I think that scope is a second focal plane scope , so yes it is going to change with different power settings . Jim

    Does'nt matter what the RETICLE is , the point of impact or the zero/zero position should stay the same thru-out the Power Range .

    that is a second focal plane scope, so yes, the power setting does change impact point. not sure what the recommended power setting is for that particular scopes reticle to be correct is?

    NO. It doesn't. It has nothing to do with ffp or sfp.

    that all u got? it matters in a mildot scope, why doesnt it matter in the ziess "drop reticle" scopes? and explain why, just dont jump on somebody if their wrong.

    He asked if the poi changes. It doesn't. Zero is zero. Now if he had asked about the reticle graduations changing, that is what you are talking about. Maybe you are reading into what he's asking. I am just answering what he asked. "Does poi change?" Not meaning
    to dump on anyone.

    My apologies for being so dry in my first post. Hence my handle I guess.

    Folks, things may not be so simple with this reticle. When people ask about their "zero changing" they're typically referring to the 100 yd zero.

    As you can see with this reticle, the "zero" is 500 yds (assuming it's centered). That means the 500 yd zero won't change with power (unless the reticle is installed offset such that the 100 yd mark is actually in the center which it doesn't appear to be). In such a situation, if the scope is on low power and a deer jumps out at 100 yds and you use the 100 yd mark, you'll likely put the bullet at its feet.

    In my opinion such a reticle in a SFP scope is an accident waiting to happen unless all you do is target shoot on max power. In FFP, so all the marks are valid all the time, I could really like it.

    Again, that's assuming the reticle is centered which any owner should be able to verify easily.

    So, if i zero the scope at 500yd it will be good at 6.5 and 20x. but to use the range marks in the scope i will need to know the holdovers at a specific magnification.

    Thank you

    You have it exactly right for a SFP scope, for a FFP the power wouldn't matter for holdovers.

    That scope is SFP. The center cross hairs won't change zero with a power change although some scopes, even expensive ones from time to time, will do this. Suffice to say they SHOULD NOT change POI with a power change if the scope is designed and working properly.

    However, the remainder of that reticle will change POI with a power change, which is a mess! One of the many reasons I like FFP scopes for any ranging style reticle. NF and Zeiss have this great concept in their drop compensation reticles but they put them all in SFP scopes which just makes no sense to me at all. Way too many things to keep track of and way too big of a chance of a mistake!

    IMO the MIL or MOA ranging reticles setup in .5 MIL or 2 MOA hash marks in an FFP scope is the very best concept for a drop compensation reticle.

    Just wish I could get more companies to agree! :)

    The companies may not agree, (or others) but I was pretty excited about the NF Velocity 600 Reticle. Less so after I found out it's SFP. I was looking to put it on a rifle for quick use, no time for dialing, kind of hunting.
