Can anyone explain this

[startrek1761d]

Both shot at same time, same rifle, everything is identical except one has thread protector and one has muzzle brake. I don't see how a brake can reduce sd.

What is the chambering? Not moving very fast for 140s. That one faster round really throws things off. Not enough shots for me to gather much. Interested to see what others say.

With only three shots per test, way too little data to actually come to a conclusion.

Next three of each could be opposite.
You could have had the best three rounds for one test, and the worst three rounds for the other. Shoot 20 of each and report back.

As mentioned, too little data points.

Well, Since they were shot from the same rifle at the same time, maybe the atmospheric conditions in the parallel universe the second rifle was in were slightly different.
