Help with Bushnell DOA reticle

[bronko220002]

I have a 3-9X 40 Bushnell Banner 2 illuminated reticle on my CVA Scout 45-70 and would really like the to find out what the spacing is on the reticles or a way determine what the spacing is.
I'm thinking getting a big sheet of cardboard and marking a vertical line then put heavy lines about every 6" or so. Set the target at 100 yards and put the center crosshair on the top line then take readings for each successive line. From there I can say that, for instance, if the first stadia line is about 6" down its 6 MOA (approx), second stadia line at 12" then 12 MOA approx.
Do that for the rest of them and use the Hornady ballistics chart to plot what each line represents. Like for my load 1 = 175 yds, 2 = 215 yds, etc.
Or I can dial my power ring down so the lines fall for in line like 200, 250, etc.
What say you all?

I'm not expert, but to my understanding, sfp scopes are only accurate at top power. That's not to say you couldn't do as u say, but it will.take quite a bit of shooting to determine the point of impact at different ranges.

Scope tracking is sometimes a lesson in futility. I use a ballistic program and start with a 100 yd.zero. I move my target to 150, 200, 250, 300 & 350 yds. I generally need to adjust the BC because I already know my velocity. The two scope I actually use the elevation adjustments do ok. I print a dope card and it stays with the gun.

Way I do it is zero center at whatever distance I want it to be then laser next distance I want to setup at. Like 1=100 2=150etc. Hold 100 yd zero at every distance then measure the drop and mark it large enough I can see it clearly through the scope lens set scope xhair on 100 yard zero point and see what point lines up with where the 150 hole is. Then repeat for each distance.
