I have one that is sighted a little over 1 1/2 inches at 50. Seems to be dead on at 25 and 75. At 100 I only shoot if they stand and I aim about a gopher high. I don't shoot many long shots because when I get around to shooting them there are lots under 50.
I no longer shoot ruffs with a .22, but if I did I have an old single with iron sights so I don't have to think about a sight that may be 1 1/4 inches above bore at close range.
I would think that with modern reticles like the BDC one could have rifle at zero for several ranges.
