On a more practical note it seems that there is a barrier every couple hundred yards to really succeeding in the pursuit of precision. I really found out to 400 not that difficult but 400 to 600 definitely took a step up, wind meter was a great aid and really helped, laser rangefinder starts coming into play. Then the jump to 800 and then your spending time with the above tools as much as with your rifle, I found this was the range that really started to expose my rifles ability and I had to really work with it, a MOA rifle will not teach you to shoot sub MOA, it took getting my rifle and load to a sub half moa for me to tighten up all my other calls at this point. At 1000 yards my method for doping and method for getting quality ranges and my muscle memory and interaction with the rifle started taking over. It's really a building block process, every once in a while you have to step back a few steps and rebuild something because you find you can progress on the track your on, ballistic apps really took me some time to wade through but that was when the first apps started and prior we basically had Xbal and Patagonia.
I would really encourage anyone pursuing the precision part of hunting to go full in on an app, charts and basic stuff really have walls that you should stop on, a full featured robust ballistic app is worth its weight in gold IMO, a real time solution is invaluable!!
