I am sure there are thousands of techniques people use however this is what I have come up with...First and foremost I use a ballistics app as most people do and this is primarily due to varying angles. I have learned over the years that angles have a great deal of affect on trajectory is most air rifles.
When I go to a permission, or even squirrel hunting I am faced with taking shots at not only varying distances, but varying angles and have come up with a quicker solution then, spotting the target, entering the data into my phone, and getting a solution for one shot.
I downloaded an image of my scope reticle (Hawke AMX) and then went into my ballistics app and started punching in varying angles and distances to see how much the POI shifts to narrow down a "margin" that I can utilize easily. I have found that 0-10 deg angles for my rifle hardly shift POI and then from 15-25 deg angle, they all fall within an acceptable range of each other. So I simply take two images of my reticles, pop in the numbers for those distances at those angles and now I have something to cover mostly all my shots at a glance.
Disclaimer: I am fully aware this is not exact, nor that scientific, however this works for taking shots on game/targets/pests that don't give you the time to go finger banging your phone for a solution.
