So as a check, chamber a round of the 108 and close the bolt fully and then eject the round. Do you see any marks on the bullet where it could be touching the rifling ?
You might even coat the ogive area with perm marker first so you can clearly see where it's hitting...if at all.

And if you are willing to sacrifice the round you can turn it into an OAL checker.

92 thou difference for only 3gr heaver is a lot. That is one stretched out bullet or Hornady really wanted to stick it out there.

The pics are a bit low res but it looks like you have a lot of cratered primers as well? Do you see that on the 103’s? Looks like there might be some ejector swipes as well? The blown out ones have all sorts of soot left where the ejector is and a ring has formed on your bolt? Everything sure points to pressure, and no matter what Hornady says you might want to avoid those rounds for now. The 6 Creed is running some really stout specs to beat .243 velocity and are on the bleeding edge…
