Hi 5r milspec, welcome to the forum.
You want to confirm that 14x is the setting to use when ranging.
10 Mils covers 36" at 100 yards.
I checked my Leupold mildot scopes this way:
Set up a 36" tall piece of paper at 100 yards.
Put your rifle in a sturdy rest and set scope on a low magnification.
While viewing the paper thru the scope, slowly turn the power ring till the full 10 mils of your scope cover the paper from top to bottom.
That is from the bottom of the top thick post all the way down to the top of the bottom thick post.
You may find that your scope covers 10 Mils before it gets to its maximum magnification.
My 6.5 to 20 covers 36" on the "X" at the 12x setting.
Be sure to write down where this spot ends up.
I'd also suggest getting a mildot master: Mildot Enterprises Mildot Master Range and Bullet Drop Calculation Guide - MidwayUSA
