Something to consider is the effect your zero has on distance. I know that KHSC only goes to 100y and 50y, but with that said, you could hit 50 and push to the 100 with the same zero.
At that range, given applied marksmanship, I would say that 1" to maybe 1.5" groups are good. At 50m, you do not need to make adjustments for wind. It is only at the 200m or more that 5.56 will begin to "drift". There is a video of Travis Haley discussing the differences between zeroing optics, both red dot and iron.

I use the American Eagle red black box for most of my reference shooting. 55gr 223

Part Number AE223

Most out of the box rifles in the under $1000 range are usually 5-shot group at 1-3" at 100 yards with the reference ammo.

last time I used wolf I think it was 1.75-4" at 100 yards. Very inconsistent.

I normally take apart the upper and check everything and reassemble MY WAY. and when testing the same rifle I get SUB MOA or at least better than 1.25"
This is on the Colt 69xx & Sporters and M&P15 Rifles.  I have found a lot of these to have loose barrel nuts and loose barrel to upper receiver play.
Just had a M&P Upper in here where the factory barely tightened the barrel nut.  the barrel could be moved from side to side.

M193 ammo normally doesn't pull real tight groupings. 1/4-1/2" difference.

Top is with red dot, bottom is iron sights. All @ 50 yards.
Except the 3 touching the red for the bottom target, that was with red dot. So im not consistant.

What is the last thing you see before pressing the trigger - the target or the sight (irons or red dot) ?

What is your level of experience in shooting a rifle for precision?  I would say at this point that you should let someone else with good familiarity with an AR and that has good precision shooting skills to shoot the rifle using a quality ammo type when doing so.  It really is the easiest and most efficient way to troubleshoot and to be able to immediately eliminate certain variables.

Combo of red dot and target in background.

For iron sights, combo of front post and target.

Total noob   :shake:

That's why I was wondering if for my type of rifle and ammo, is the hits acceptable?  I know I'm not going to hit the bulls eye with 1 moa grouping.

My bet is "user error".

Most rifles are far more accurate than the shooter.

I would suggest two things.

1) Try and sight it in with a higher magnification scope. This will instantly tell you if it's the gun or you.

2) Try different brands and grain weights of ammo.

Typically a 1/9 twist rate will do well with 55 grain loads but even in the 55 grain ammo, you can and will get huge disparity between brand A and brand B or C, etc...

If you tried wolf, try also federal or Winchester or another comparable, high quality brand of ammo.

Also try out 62 grain ammo to see if the change in grain weight works for your rifle.

Understand that every rifle has a favorite ammo. Your rifle might like federal American Eagle 55 grain, while "your friends exact same make and model rifle" likes Wolf gold .223 55 grain.

To me the best part of a new rifle is the research I do to find out what ammo my rifle likes best.
My SCAR 16 for example will easily shoot 1/2 MOA all day with PPU match 75 grain, but I can't get 2 MOA with 55 grain federal 223 on the same rifle.

Good luck, shoot straight, and be safe.

Your number one Option for Personal Security is a lifelong commitment to avoidance, deterrence, and de-escalation.

Someday someone may kill you with your own gun, but they should have to beat you to death with it because it is empty.

Combo of red dot and target in background.

For iron sights, combo of front post and target.

We can't focus on 2 things at once. The last thing to focus on is the front sight or red dot right before the gun fires. The reason being is that it is the last reference point to where the gun will shoot at. Think of looking down a straight line with the two end points. Your eye can discern minute details such as movement of the front sight. That distinction and the control of your trigger is what contributes to your call.  Your focus should be hard enough to see the fine details of that front sight. The texture, the edge of that post. Where that front sight post goes is where your shot likely went - given the rest of your position is consistent.
I find that as I got older, the harder I needed to focus on that sight.

Here's a tip from the USAMU in regards to what I discussed

Top is with red dot and bottom with irons.  50yrds.

So groupings tightened better around POI.  Things i did differently:

1) lowered brightness on red dot
2) used tip of finger on trigger
        A) found out i need a bigger handgrip
3) focused on front post/red dot.
4) had cheering support of macsak

Even hit gong from standing position.

Looking good now.  Next you have to do the same unsupported.  Keep challenging yourself and moving the goal post back.
