Thank you schnorchel, you are a hero. I spent days searching for some solution and was going crazy thinking I was the only one with this problem
Your mod adjustment is just what I needed to make the ROAFB useful. I am now measuring with accuracy within 1% to 2% which is quite acceptable!
However I do need to ask about the red marker which appears to be labeled "1.5x" on your wheel. I assumed this was the reference if using the 1.5x magnification on the scope, but if so, I think it is in the wrong place.
The magnification ratio between 1.5x and 6x is 4:1 so for each mark in 1.5x you would count 4 in 6x. So the RAOFB reference line for the 1.5x should be where 1/4th of the value under the primary red reference line. In the case below I measured 12 clicks in 6x scope and 3 clicks in 1.5x scope. For the range to stay true the 1.5x reference should be down at the 3 on the middle inner ring. Roughly between the "n" and "m" of the phrase "Basis in meters" on the outer ring.
Would you be willing to make a change like this?
