I'm sure this dead horse has been beat plenty of times! I was running the numbers today to try and figure out which BDC settings to order my turret. The load is .308 Win, 150 gr ETips at 2850 fps. I decided to graph the click settings for a bunch of different altitude and temps. I've always thought it was funny when people complain about the slight differences you get when you change conditions. In reality out to 600 yards (many may call this medium range but I personally consider it my max) the differences for the various conditions are within a click up or down on a 1/4 MOA click scope. I even added an extreme condition of 10,000' at 60 degrees (not likely anywhere I hunt during deer season!) Don't know if this pic will show but looking at the data you'll see a BDC for 5,000' at 60 will theoretically work for 2,000' at 90 degrees and 8,000' at 30. You're within the one click zone for all those ranges and conditions. In other words a turret for 5,000' at 60 degrees needs 68.7" at 600 yards. That is just above the 68.6" for -1 click from the 2,000' @ 90 setting and below the 69.1" for +1 click from the 8,000' @ 30 setting. For all these conditions you should be within 1 click off which at 600 yards is less than 1.5" For big game hunting that seems like nothing to worry about. and having MOA comeups probably won't get you much closer due to the coarseness of the 1/4 MOA adjustment.
