What is the effective target range of a 7.62x51mm BA rifle?
Since that’s one of the calibers used by military snipers, the generally accepted accurate range is 800 yards, with 1,000 yards being possible in some cases. 800 yards is nearly half a mile and getting to the point where you can reliably place shots where you want them at that range is challenging; you’re going to be doing a lot of practicing.
