Thanks for sharing your results.
I would add my vote to the others on the forum that after break in any new Grendel be tested first with Sierra 120 Match King bullets.
That will give you the best accuracy benchmark. (find out first at what OAL they touch lands).
If the 120MK won't group under an inch at 100 yards there is a problem in your build/barrel/rest/mounts/scope/rest/shooting technique.
