At 1000 yards, (which is what the OP asked about) the 308 arc is between 30-35 ft above the ground.
Fine. How do you suggest all the ballistic software out there get changed to do that? Berger's and Sierra Bullet's software is probably the best available. They put the maximum ordinate for .308's zeroed at 1000 around 12 feet near 600 yards.

If what you say's reality, then please explain why coming up 23 to 24 MOA from a 600 yard zero to a 1000 yard zero puts bullets from a .308 thirty feet or more above the 600 yard target when 23.5 MOA at 600 yards equals 11.75 feet. Download Berger's software and see for yourself.

I already know all that other stuff you mentioned. And more than a few of us High Masters in NRA long range matches have confronted David Tubb about his areas of ignorance.
