Grendel on the Cheap

[A5BLASTER]

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.

Yea there is no absolute like that with any bullet. I have 2 barrels that hate the 120 mk but shoot routinely under a inch with 120 fusion, 123 eld-m, 123 scenar, 123 nosler cc, 85 trex, 129 ablr.
