Center meaning top , rightI don’t understand the question, but typically I sight in the center reticle for 20 yards.
From there, I see where the other reticles hit and just remember that yardage. If you can adjust, then adjust.
Typically if center is 20, the others will be approximately 10 yard increments.
Mine is 20, 30, 35, 40, for example.
Yep.Center meaning top , right
What kind of scope are you using and does it have a “speed ring” on it? The two newest scopes I just received want you to set the top crosshairs at 20 and then it increases in 10 yard increments. So it appears based on your yardages and crosshairs you are using, its setup the same way.
