Re: Ian... is an author...for Nikon???
To my simple mind the parallax dial is used to fine focus the target and the screw-out eyepiece is used to fine focus the reticle. I know what you are saying, but with the third turret scopes I just ignore term parallax altogether and use the knob to sharpen my image, probably doing so removes parallax. I do the side to side-up and down check occasionally but the Nikons, MK4's and NXS that I usually shoot don't seem to show any significant parallax to my eyes.
Glad that you are happy with the Nikon, you have some fine optics and know what the optical standards of top-end scopes are. We have a lot of Nikon tacticals going and they are just plain doing a fine job. Hope you get the mildot master thing straightened out quick.
