It’s just the difference in harmonics from bullet to bullet, once you select your final load adjust your scope accordingly
Thanks, Steve I hope I do get to feeling better and hope your brother gets better as well. I don't ever get sick and when I do its bad, but I must go, go, go!ohihunter2014,
First off I hope you get feeling better! I talked to my older brother in PA last night and you would swear he had pneumonia they way he sounded and was coughing.
That last group you posted knowing you aren't using wind flags and the equipment you have is very very respectable group at a little over 1/2". I would do exactly like you say and simply keep shooting going forward and keep an eye on your overall accuracy level. I suspect what you call a flyer in that last group may not be a flyer but "in the group" sort of speaking.
THR member "bds" has been posting lately about 10, 20, 30 or more shot groups for a 9mm to get a truer overall picture of accuracy level. Yes he is doing it with a 9mm pistol but somewhat of the same theory applies I believe. You are trying to shoot 5 shot groups and sometime 1 or 2 get loose and its driving you crazy if you just look at the 5 shot groups as individuals. But what if you theoretically shot 50 perfectly aimed shots and your end result of all 50 shots is this same 1/2"? Then that "flyer" in your last 5 shot group isn't really a flyer in the grand scheme of things. Hope that makes sense. Or if you keep your target lay the multiple targets on top of each other lining up the same aiming point and you should be able to overlay all of your 5 shot group that are off to the right over each other and "see" and bigger overall picture of the rifles capability. But wait to do this after you have fired some more groups now that you fixed the parallax issue.
The left to right movement of the group probably is harmonics as Jim eluded too. It concerns me a little as this should show more up and down in group placement rather than left to right. When you get a lot of harmonic changes in the horizontal plane in a rifle that I'm trying to really tune, usually causes me to look at barrel to action squareness, bedding, (we've already covered parallax), something mechanical, or inclusions in the barrel itself. But again you are shooting a complete factory rifle and they aren't perfect. So I think your plan of simply stop thinking, and keep shooting what you have is a good idea. Like I said before 1/2" groups is nothing to sneeze at with your given equipment.
I like benchmark in the 223. I jsut fired several hundred rounds in my AR during a carbine/pistol transition class on Tuesday. After running the rifle hard I didn't have a huge buildup of carbon. Overall the powder burns really clean and the muzzle flash is really low from a 16" AR barrel. Obviously this doesn't concern you and your rig going after chucks, but knowing it burns really clean is a good indicator also as well as the accuracy you are getting.
Keep us updated of future testing/results. getting maximum accuracy out of a bolt gun is my life passion. I like and train with my AR and pistols for defensive purposes and have fun with it. But sitting down at a bench or open fields and squeezing of rounds into tight clusters at paper or varmints..... that is a special place

I keep forgetting to put something out. I shoot down in a bowl where its trees 100yards wide all the way down the range, so not really any wind. I will try and remember to put a flag out tonight.Very good post by Steve,
As pointed out the lack of wind flags will keep you guessing - is it me my load or the wind.
Take a look at my Avatar you’ll see a 1.9 five shot group at 600 yards and what just a tiny bit of wind can do to an otherwise excellent string.

Dang Boss, you got more flags then Mike Ezell..Anyone who thinks the wind does not affect the bullet at 100 yards has never shot a one hole capable rifle over wind flags. Just can't convince them wind moves bullets at 100 yards. I have given up trying. I tell them, they boo hoo it, and I go away.

My friend always says to light a camp fire then tell me there’s no wind.I keep forgetting to put something out. I shoot down in a bowl where its trees 100yards wide all the way down the range, so not really any wind. I will try and remember to put a flag out tonight.
