Grendel II Accuracy and preferred loads - nincomp - 04-19-2014
As long as it is OK with the Mods, it would seem a reasonable idea to begin putting this info into a single location.* Hopefully, this will prevent the need for plowing through long threads that are largely about something else in order to find pertinent information.
As of early 2014, there is a lot of speculation about the performance of "Grendel II" chambers, some of which come with new barrels, others from the modification or "scraping" of existing ones.
[U] Please include information about the barrel, including the manufacturer or similar info (like "Stoner"), type of chamber, whether is was sent out for modification.
[/U]
Hopefully, it will be useful to get enough information to help owners of these barrels choose which factory loads are most likely to provide the best accuracy.** If it is discovered that these Grendel II barrels perform well with the same loads as the 6.5 Grendel SAAMI-spec ones, so much the better.
I hope that one of the Moderators will step in and let us know if this thread should include reloading info. WARNING: DO NOT EXCEED THE PARAMETERS OF LOADS TESTED AND PROVIDED IN RELOADING GUIDES OR BY MANUFACTURERS. Damaging your weapon or yourself can ruin your day and/or result in soiled underwear.
* This thread might be considered part of the 6.5 Grendel Ammunition and Reloading section, but we don't know yet if the Grendel II prefers certain bullets or factory loads.
** Of course not all barrels prefer the same loads, but this would be a place to start.

I grabbed this information from another thread. Hoping to see more.
waveslayer Wrote:There has been data posted. I posted my results the week after I had my throat scraped. I had pressure sings at 31.4 grains of CFE with the 123 SST bullet. After scraping I was able to go up to 31.9 before in had any pressure signs. Same seating depth. The velocity had very little change. I settled on 31.2 grains of CFE and shrunk my groups from .516 to .388. So the results are in.
I'm not a fan of the new chamber but stating that the results will speak for themselves has already been proven awhile ago.
Would I ordered a Grendel II? No, I will stick the the normal Grendel. Am I upset, I was until they fixed it and now I'm a happy camper.
