Re: schmidt and bender reticle
It would appear that they only come in Mil. From the S&B website:
Converting to minutes of angle:
This enlarged view of the Mil-dot reticle shows dimensions of the dots and spacing. Mil-dots on the vertical line can be used for holdover estimating if the mil spacing is converted to minutes of angle. To do this, multiply mils by 3.438. For example, 5 mils is (5 x 3.438) or 17.19 moa. Complete conversion tables are included with each scope.
