I can't seem to find the video, but I think I remember Travis Hailey doing a good clip on a, I think, 36 yard zero for general use. Maybe someone has this in their links. It might have come from their adaptive carbine course, but I am sure I saw it somewhere else also.
edited to add, I found the original thread about this, however the video is gone.

Maybe someone can find a copy of it.
Wow.Here's another one.
Uh, no; gravity does not "take over" at some point. It's there, exerting a (for this application) constant pull on the projectile from muzzle to impact.As gravity takes over, your round tends to drop.
Wow.
I know you meant well, but that video was far from good. He went off-topic promoting a web site build business for minutes at a time. He promised to explain why there can be a non-intuitive rise in point of impact at longer distances when the target is further away than the zero distance...then failed to follow through on that promise. In fact, he never mentioned the impact of sight height above boreline.
And I nearly fell out when he said:Uh, no; gravity does not "take over" at some point. It's there, exerting a (for this application) constant pull on the projectile from muzzle to impact.
Colloquial phrasing among friends is fine and dandy but when you're purporting to provide information to people on how to zero a firearm, isn't a little language precision pretty much mandatory?
He managed to cram 90 seconds, at most, of information into 13 1/2 minutes of out-of-context ramblings, wildly-scrolling screenshots, and on-topic wording that was fractured, out-of-teachable-order, and just plain poorly phrased. That is an amazing feat, on multiple levels.
Everybody's a writer and publisher these days. Who killed all the editors?
Theres a link ive found from a guy that designed targets for zeroing the pro, each square has a guide how many clicks to get center. They are free to print.
