I'm relatively new to long range shooting, but not a complete novice to shooting in general. I have been working on learning to make long range shots 600+ consistently. There is no substitute for going out and shooting and that is what I've been doing. However, using some apps such as "Shooter" and "Ballistic AE" would be nice to at least have a reference point. I use mil R&T I know when I'm zeroed at 100 yards, my elevation adjustment is .5 mil up for 200 yards. However the firing solutions I get from both apps is to adjust down .6 mil. that doesn't make any sense to me, and I can't figure out what would cause that value to be so off. I'm shooting a custom 6.5MM Creedmoore w/ a Steiner 4x16x50 scope. I'm using factory Hornady 140 grain A-max bullets and the hornady site solutions are much more accurate. I'm shooting ranges longer the 200, but once I know the apps are that much off at 200 I just don't pay attention to them anymore and focus on what actually happens when I pull the trigger. I would like to figure how to make them accurate, I've tried all sorts of different things, but I'm not getting accurate solutions. Thoughts?
