I recently purchased a mildot reticle Nikon Buckmaster 4.5-14x40 scope.

 

Is is correct to assume the mildots are calibrated for use at maximum magnification?

It should say, or have some marking on the magnification it is set for. My Buckmaster mildot 6-18x, the mildots are used at 12x magnification. Also, Nikon gives a mildot guide with their mildot scopes...

OK, I checked and you're right, it is marked on the magnification ring, also at 12x, thanks!
