If you are having problems figuring out what data to put where, let me know and I can input the data for you and generate the PDF's of the reticle at dfferent magnifications.
Looked it up and figured out that the mil-dot reticle is calibrated for 14x on your SFP scope.
Here is the reticle chart in MILS (mrad reticle) for FGMM 308 175gr SMK HPBT (see attached PDF). Your reticle at 14x is "similar" and the mil dots match up to the major MIL hash marks (i.e. 1, 2, 3, 4) on the mrad reticle.
You'll also notice that the following image (right) is pretty close to the reticle chart, since the image is set up for 168gr projecticles.
