Assuming you 1, have a duplex reticle. 2. have a ballistics table run
1. With your 3.5-10 Leupold on 10X, the distance from the center cross to the point where the fine/bold meet is 5.4MOA.
2. With a ballistics table run on your load, You can use that known and fixed 5.4MOA number to slide windage as necessary and even for a quick holdover if you're not dialing elevation. Quick and dirty rule of thumb, assuming a 200yds zero, the duplex intersection @ 6 O-Clock when on 10X is pretty close to dead on @ 400yds.
Would it be true then, that at 5x zoom, the vertical post would represent 2.7 MOA? Just trying to figure out different ranging options.
