I know it will climb but how much? Our humidity in Alabama is also high right now it stays at around 70% or higher (90% here latley) so that will have an impact as well. I know from a short range standpoint not much will change but if I were to zero at 200 (like I normaly do) what would I expect as well. I am shoot a 7mm factory loaded Fed. Prem. with a 160 accubond.

Elevation or wind or angle, etc. will have very little effect inside 200 yds. The farther out you get the more effect it will have (exponentially).

As said previously, there is no substitute for practice in actuall conditions when it comes to LR.

Good hunting
