I'm getting back into shooting and hunting after a 25 year hiatus, I've been pouring over and sucking up as much information as possible looking at guns, cartridges, ballistics, scopes and whatever else I can read. I've read everything I can spending hours a night over the last 3 to 4 months and there is one thing I haven't found an answer to and so I decided to ask even at the expense of sounding silly. When looking at rifles and how "accurate" they are they tend to refer to grouping in terms of MOA. I get the MOA angle but a tight group is a measure of precision not accuracy. A group that is <.5 MOA but 3 inches off the bulls-eye is precise not accurate. A group that is <.5 MOA and .5 off the bulls-eye is both precise and accurate ( I teach Physics and Advanced Physics so maybe I'm splitting hairs). I guess my question is; are shooters looking primarily at groups because they can adjust scopes to move them on target? Are they deliberately shooting away from the bulls-eye? Can someone please explain why a half inch 5 shot group 5 inches off the target is satisfactory accuracy?
