Longest scattergun shot for me was back in the middle of the last century, a buzzard plinked out of a tree at about 125 yds with a Forster slug/12 ga. Dad was impressed. Front beads are skookum. I din't know it was hard to do that.
Plinked a couple dinks in a .50 pit right around 1,000 meters one day. Fella doesn't need much in the way of sights for a minigun, though some experience helps. We didn't install the sights in the OH6 due to lack of room.
So, does any of that qualify as long range?
I am..........disturbed.
