What would cause this flier.
6ARC, 22" barrel, EC tuner brake
Alph brass, 31.gr 2000MR
Rem 7-1/2 M primers,
0.002 shoulder bump,
0.020 bullet jump.
2 go into same hole and then a flier.

Has the rig ever shot tight?
Hard to say from just this much info, but is there any history that says this load should normally be in tune?

If those groups were shown in composite with a common aim point, then they are all over the place.

The overall composite diameter would be near 2 MOA, which isn't acceptable for a modern rifle shooting a modern cartridge.

For there to be hope, the two touching holes should have a common group center if we were to make a composite of all them.

When those touching shots wander all over, and one of three jumps way out, then it isn't a flyer it means the whole system is off.

When I find this on the lines and don't know the history, I drop back and ask if there is any other ammo known to baseline the gun and retest with that pet load. If that pet baseline ammo shoots, then we at least exonerate the rifle and the driver so we can shift focus to the bad ammo batch. At present, we can't eliminate the driver, the rifle, or the ammo.
 
Agree with larger shot groups.
I like to use 10. I can almost always call the real bad misses when I squeeze the trigger so having 9 more to look at is just that much more verification.
I've seen some sort of weird things happen...like a particular combination of barrel, trigger, bullet, powder, seating depth, etc....will shoot a nice 1 or 2 MOA group but be in like 2 or 3 separate real tight groups of less than half MOA each. I have found that a sort of 3 leaf clover set is not uncommon. 10 shots go into 3 separate groups.

You have some more shooting to do and more things to try with load development.

Unfortunately, the OP didn't give any information on his setup (bags, bipod, bench, prone, etc) or rifle (hunting, F class, weight, barrel profile, free floated, etc) so we don't know much.

I will tend to agree with @RegionRat in general but in my opinion, based on the target my first inclination is the shooter. Expanding on what @straightshooter1 said I am assuming that the groups are all three shots in succession. The fact that each group is moving in relation to the apparent point of aim is most likely a setup/hold issue. The flyer in each group may well be a true flyer due to load but more likely a shooter induce error unless this is a thin barrel rifle and barrel heating is coming into play. However, since the flier is going in all directions I favor the shooter versus the barrel which would more likely put the shot in the same general direction.
