Exactly, *distance and target*. Alot of the work happens well before the shot and there's tools to assist with the FFS (field firing solution) like range finders and ballistics solvers. I never use a wind meter though, I call it manually. A few clicks here and there and accurate rounds go down range. Clearly there's more than that, but I'm trying to say that a lot of the work, set-up, is behind the scenes, not in the field. 

It's a great thing to know, for me anyway, and brings confidence. Motor skills and math...Yep, a really good way to put it. I wish I could take you for a shoot. I know you'd be hooked.
