Does anyone here use their A/O for very rough range estimation, especially when using mildots and if the target and surrounding objects do not have a known height?

I was always curious if folks found higher-end A/O's to be accurate when it comes to the yardage markers.

It is completely random, you can never trust the factory markings. I have heard of some cheapo's being very close as whell as more expensive models, and I have also heard of both high and low end scopes being way off. However after you introduced this subject, an idea popped into my head.

 

What if you were to paint over the markings on the scope and go to the range where it is already measured out, and put index marks in the actual necessary parallax settings? That may help, but remember that after you go past 300 yds even with marks you are barely touching the A/O to add on 100 yds, so it wouldn't be of much use past that point.

 

It is a good thought if your scope doesn't have a rangefinding reticle. However if it does and you don't know what the size of the target is than you will get reading just as accurate as a correctly marked A/O if you just guess how big the target is.

Unfortunately the AO adjustments change iwth temperature, altitude, humidity, etc.

Good idea, but won't work.
