Powder charge 2 3 grains of powder will change everything
I agree with every possibility mentioned above. And some are a bigger problem than others for shooters. But I think Carlos88 nailed most of the issues for reloaders that are seasoned. The only other one I lean to more than the remainder issues is nodes of powder and overall cartridge length. Man if your not in a node your not doing you or the gun justice. 5 shot groups are the tall tale but 4 - 3 shot groups back to back are also. Picking the right node is a must and knowing when a node is good or not comes with plain experience. My 2 cents.
Based on what I've read thus far... I'd say it's either ignition timing, or bedding. If you're having cocking piece drag, sear drag, or some other ignition system issue... that can for sure do it.
You could also perform a primer seating depth test, as it can really help if you're right on the edge of an ignition issue.

Can you be 100% sure you're not causing there flyer. I've come to realize that most of the bad shos are human influenced. Can you be sure that you're lined up behind the scope exactly the same every time and there is no parallax? Different pull on trigger, different set in shoulder, breathing?

IMO, the 6.5 and 300 is showing signs of aerodynamic jump.
the other 2 are shooter recoil management (touch the gun exactly the same way each time or use a good sled) also heat/harmonics. If shooter is good try a barrel tuner.
I've also seen groups tighten up, if ES/SD is excellent when you change primer depth and ensure it's consistent with .0025 max dispersion. So like between.003-.0035 no under or over.

Are the "flyers" with different types of bullets? I've had luck shooting Barnes into .75-1.0" groups in rifles that shoot other bullets into .3-.5" groups. Finally I just decided that it was a hunting bullet and good enough if I needed (not wanted) to hunt with them.

my guess is that its your projectile weight
try different bullet weight or brand

i have a CR in 300WM that will group everything well. I have the same gun in 280AI that won't. Drives me crazy.
good luck

This^^^^^The two touching/ one not is because you aren't seeing the full population of likely results since you're only seeing three data points. If you continually shoot groups and overlay them, you'll see the actual size of the group emerge, and the "flyer" won't be an outlier once there are enough data points. In a way it's applying the concept of ES to group size, the group size can't be smaller than the largest spread.
A true flyer is a shot that you call as being off before you see where it is on the target. They're based on the last sight picture you have before the shot goes not being on target. You must call it before you see the result; if you wait to see the target before calling it you're excluding an otherwise valid data point from the set and basically lying to yourself about the size of the group.

How To Predict The Future – Statistics For Shooters Part 1
I actually believe the average shooter might get more value from this Statistics for Shooters serie...
see it happen all the time, the hunters who brag about only shooting one box of ammo per decade experience this on the rare occasion they go to zero their rifle…fire a two shot group…adjust their scope…fire one..
h it's not where it should be…readjust the scope again…shoot…what the &$"/* is going on here!!!! Readjust…..I use three shot groups for 100 yard verifications and adjustments. Anything further though and I prefer to send a minimum of five and honestly prefer 10 shot groups. They tell the truth!
As mentioned by Idaho Hunter1 is this happening with other bullets? If it's only the Barnes you ve tried get some easy to tune C&C bullet/s and see if that pulls group together. I personally believe after more than 50 years of shooting and reloading that the bullet is often the first thing to change up when checking a guns potential; assuming of course that you re using a powder that's in a reasonable burn rate window for the cartridge you re working with.
Good luck.
Good luck.
