bob4,
Sorry for the misinformation. Bravo 4 is right. I changed a couple more things and sure enough, at 10,000 ft my bullet does require 2.38 MOA less. Which at 1000yds is almost 25". I stand corrected, thanks.
All the data needs on the spot verification, which is why target shooters, (and sometimes hunters) use sighter shots.
Even leaving a loaded round in a hot barrel can have an impact on where that bullet lands
Normally I do change all the atmospheric settings while shooting as they are happening real time, I just had a brain fart guys. It won't happen again. johnnyk
