" Even if you have the finest .338 WTF in the world and have accounted for every perceivable variable, you are going to fugk up sometimes. Which is why I think more people should practice in the worst possible conditions they plan on hunting in, pick a max range, and leave it at that."
THAT'S IT: Simplify, practice until you KNOW it, not just think it, and "leave it at that".
Well done.
