I'm going to verify poi today at 50 yd increments. I'm using a digital scope and will also shoot a different zooms to ensure its holding the same zero. The cross hair moves and then seems to move back as you zoom in and out.

I can pretty much shoot any 55gr round through mine and it's perfect. I've shot 2 pigs and 2 coyotes with my night vision setup. The coyotes were side by side at about 130 yards both DRT. One of the pigs I shot was around 300lbs and he took 2 rounds and made it about 60 yards. Those soft points are pretty lethal.

I use the 50 yd zero with a 1:7 twist and 62gr 556. 1-4x scope (pic shows when i had EOtech on). My feeder that pigs took over is at 110. i put down 7 pigs this past season. I aim 1" low behind the shoulder at 105-120yds. Haven't missed. All 7 went down within 50 yds 3 went less than 5. Biggest pig about 100# or so.

Yep. My 5.56 AR is zero'ed at 50. So at 200 I'm back at zero. That's as far as I'm gonna shoot any much of anything with a 5.56 AR anyway.

So with my rifle configuration and ammunition zeroed at 50 I was 3 inches low at 100 on paper. I zeroed to 100 and it seems to be more stabilized from 50 and out now. So many variables that take place but my situation best resembled the first article posted. The ATN X sight is also a monster scope so the rectile is fairly high off the weapon.
Thanks for all the help.

Hmmm. That doesn't make sense. A 50/200 zero is pretty much the standard for a battle zero. I wonder if the digital scope on the X sight messes with something.

I would also look to at group size to make sure the scope is actually holding zero and shoot all groups regardless of distance at the same zoom level. You want to remove as many variables as possible.

X2! Lol.
I've read this thread twice and I'm still confused - lots that's not making sense to me. 3" low at 100 when zeroed at 50?? Wth? Lol. Maybe shooting subs?
If your shooting pigs at 125, sight it in at 125 because something doesn't seem right with the rifle/scope/load combo.
