Agreed Art. Hold over is a different story. That is what I do with my 223. I have a mil dot scope,have it zeroed for 200 yards and can shoot very well out to about 450 with it just using hold over. How ever-zeroed at 300 and then going to 1000 or 1200 yards, The hold over option is no longer there. Bullet drop is way to much for that. Which leads me back to what I first said.
Hold over out to 400 to 600 is possable ( no scope adj is needed) farther than that and a level scope is needed ( more than eyeball level). I also eye balled my mounting till I started shooting 1000 yards and more. That is when I found out it just don't cut the mustard.
