Uh huh.
Well, just like you can't have a high performance car that also gets good gas mileage, a rifle that will deliver at extremely long distance isn't going to work well when pressed to serve duty at very short ranges.
1,000 yards is a pretty long distance. You can't learn how to shoot that far from a book, the internet, or video games. Even if Mars and Jupiter align and you find that for some reason you both need it and have it, unless you've actually shot those longer distances and got good dope for your rifle, you won't make any hits with it.
But hey, at least the Facebook pictures will look cool, right?
