After I ordered my new Tract, I played a bit with their online calculator. Plugged in the figures for Hornady factory 123gr SST 6.5 Grendel ammo. Using the SFP Tplex, I found some good combinations of zero and scope power that will allow me to use the bottom post as a holdover at longish range (for me). I'll have to verify it on the range, but it's a nice feature.
I know guys have been doing the same thing for years on their own, but the mathematically-challenged like me will appreciate this, I believe. It doesn't limit you to 100 yard increments either, but rather 10, IIRC.
We can't all be mathman.
