and 8000 ft for elk, then compound that with various temperature combinations that I might experience. Even if I was able to do that my barrel would be ready to be replaced by the time I was finished.
As an experiment when you get your program set up just for kicks just change the elevation and humidity for everything you say in your "quote" above. I think the differences you will find will only be a few inches which will keep you in the kill zone of the animal you will be hunting. The big difference comes in when you shoot up and down hill at big angles.
I sighted in my rifle at about 800 feet in elevation dead on at 200 yds. Then when I got to North East Wyoming I checked it again at 4,500 feet at 200 yds. and it was less than 1/2" different with the temperature and humidity about the same in both Georgia & Wyoming.
PS: Why do you think that Huskemaw
and others sell so many scopes that have a custom turret made for your drop chart? It will only cost you about $100 to get one for your scope. Try one and you will never look back. But be sure to shoot at different distances with YOUR rifle and MEASURE what the drop is from your ZERO. DO NOT USE a program to get the drop measurements. Every rifle shoots differently.
