RE: We speak of long range in here so.....
What I really get a kick out of are "hunters" that come into our shop and buy something like a 30-378 and want us to sight it in for them.[&:] We go to the range and sight in at 100 yards. When we ask them where they want the impact to be at 100 more often than not they tell us "dead on at 100".
They buy a rifle capable of having a +-3" point of impact out to 350 yards and zero their rifles at 100 yards. And they wonder why they miss everything they shoot at.
