Add: If BDC knobs always worked as intended then everyone would have them, but they aren't reliable IMO. And judging from what I can see in all the diagrams presented they're going on the basis that the shooter will be doing hold offs, not using their BDC knobs.</div></div>
Really! Your perception equating precision with practical is novel. Precision, when defined as hitting exactly where aimed, is an antonym to practical. That's because hitting where aimed exactly, except at zeroed point and the earlier point where line of sight intersects trajectory from a bore at a greater angle than horizontal, will always require an adjustment from initial zero to compensate for effects on trajectory and trajectory itself. This adjustment may even be necessary when a BDC function is present.

For any who choose to exploit it, good hits on the E target at 600 meters are indeed possible. The ACOG's BDC is magnificent too. <span style="font-weight: bold"><span style="font-size: 14pt">These sights are of course designed for a particular cartridge driven at a specific velocity.

Where did I say that no adjustment would ever be required? Also, I don't see how "precision" is the opposite of "practical" even with your loose interpretation.
Your advice is based upon the assumption he's using standard issued equipment with standard issued ammunition for personal use? You just stated "generic BDC's" which would likely be what the average civilian is using in combination with non-mil ammo are suspect. If BDC's were so great then why don't most people use them. You're basing your opinion on the matter on your own skill level and equipment that might not be what the average person is using.
And I don't know where you pulled anything that I said as construing that hits at 600 or any range for that fact weren't possible. I never said anywhere that adjustments wouldn't be needed. I said judging by the diagrams they would be doing hold-offs which if you actually go pull up the diagram it shows how to hold-off and where the likely hit will be. I still maintain that by your method most shooters will have difficulty maintain sub-moa accuracy which was the entire point.</div></div>
You seem to want to make an argument on unarguable facts. First, I have no preferred sight adjustment method, I do what the scenario dictates is appropriate; and, second, most shooters will have difficulty getting sub MOA much less maintaining sub MOA accuracy no matter what aiming method is used. The OP wanted to know what distance shooters here zero their semi automatic rifles. Since many of these are AR style guns which do indeed come with a detachable carry handle BDC, a shooter would be wise to come to an understanding about the outcomes which are possible from using this device properly. Properly meaning to set the sight for a 300 meter zero so as to have a BDC function too. Now, considering that the M4 and M16 A4 are most useful for KD and UKD E sized targets inside 600 meters and understanding that good hits are possible to 600 meters with the BDC adjusted properly, setting the sight for proper function seems like a good idea, even if there's a need to hastily re-adjust the sight for, as you call it, a "precision" hit. But, get real, the term precision has very little meaning in context to a good quick hit at SR and even many MR scenarios. But, for MR and LR scenarios where a BDC function is suspect, no matter what the initial zero, if a hold off is not appropriate, the sight will need to be re-zeroed to distance. And this fact simply makes your comments moot. You'd be just plain stupid not to re-adjust the sight for the actual distance. This makes me think you have little experience with the concepts discussed here; and, perhaps, your notions of what will get the job done are just what you've heard or read somewhere. Please share your credentials if I'm wrong. I'm certain you have no experience with the detachable carry handle BDC as you apparently do not know that it cannot be set to any other than a 300 meter zero for the BDC function to work.
