Not sure if this would be the right thread to ask but I’ve been thinking about building a long range gun, I’ve shot .308 out to 1,200 yards before but was thinking about doing a 5.56 build. Had anyone ever shot that round out to 1,000 yards ? And if so was there anything special about the rifle ie. barrel, hand load or factory loaded ammo, muzzle brake, trigger etc. any help would be appreciated.
