I have also heard the range was more like 300 yards. When you look at
the ballistics of the 5.56 (.223) you see that out beyond around 300
yards the bullet starts dropping pretty fast. Unless he was shooting
tracers and walking the rounds in it is unlikely they would have been
that effective. I read one person saying 1000 yards and that would
have required holding 50-60 feet high.
This was a fat retired clerk, not Chris Kyle.



"Better to think first in terms of mid-range, in the 400- to 600-yard
ranges. For this type of shooting the .223 is ideal. In fact, there are
shooters doing outstanding work at 1,000 yards with the .223 cartridge.
But this is post-graduate stuff. For now let’s stay in the medium ranges."

The shooter likely wasn't targeting individuals, but, rather, just
shooting in tight bits of crowd. And I thought he had .308 rifles, too.
Range wasn't an issue.

You are talking about bench rest shooters (sighted in at the range
they are shooting at) and this guy was shooting off hand with a bump
stock. At 1000 yards those rounds would have been landing in the
parking lot if he did not use tracers or something to walk in the
fire.
At 300 yards he could shoot point blank and only be a foot or so off.

You don't need much aiming and sight windage when you're spraying..223 down a huge crowded hole like that

I am not going to do the trig right now but at a 17 degree angle, 60
feet of elevation is a pretty wide swath of the ground 1000 yards
away. It has now been established that this was ~300 meters so this
whole thing is moot anyway.
