This is a question long unanswered for me.  When sighting in at 100 yards it has been said to zoom in to the highest setting on your scope, lets use 9 for example on 3x9-40 scope.  Once the rifle has been zeroed using the 9th setting can you use the other settings 3 through 8 with the same point of impact ?,,Ive been told no on more than one occassion but it just doesnt make sense to me since i thought they were for zooming only. I've been afraid to remove my setting from 9 on my old scope for fear of losing my zero.

in the 3x9 range you won't see much change, however sfp scopes to exhibit the effect of raising the bullet impact with a decrease in power. this is the basis of leo BAS system and varmit reticle. usually it takes a pretty good drop out to 500 yrds and a scope of descriminating at this range to tell the difference. A much bigger question to me would be if your scope showed problems, if if would be due to this effect, or just a reg. run of the mill 3x9

If you're using a good quality scope, its zero shouldn't vary through out the powers. What's the point of having a variable scope if you can´t use the different settings?

In a low quality scope you can expect zero changing. If that happens, you have to keep it allawys in the same X  (or get something better!)

the low quality scope has points of impact change due to other reasons than inherent in the sfp designs.

I just purchased a nikon prostaff 3x9-40 bdc, hopefully it will get the job done with no error.

the amount of error depends on the gun, and how accurate the load/gun are. grouping at 100 yds is just a long pistol shot. most shooters would not be able to pick up on it-- if the gun, the load or the scope was the problem. don't worry about it just go have fun.

I have to agree with Dale, go have fun.  This is getting bad, Dale and I are agreeing on too much.
