I suspect this has a lot less to do with the various chambers. Nobody else was raising a flag when they came out and didn't until now. If anything the standard response was "6.5G = .264 LBC."

PPU is going to have to substantiate why their ammo all by itself is the only one to have this problem.

Quoted:
Just got an email from PPU saying it was 2015 and newer. so anyone with older ammo is good.

I noticed when sizing some of the newer brass that it wants to fold up down near the web, very soft.



Good for hunting or competition brass.



It's also a good opportunity for them to transition to a Small Rifle Primer like everyone else.



There are 37 factory loads for 6.5 Grendel, including AA, Black Hills, Federal, Hornady, and Wolf.



PPU makes 2 of them, not including the discontinued 123gr SP load, which had a lot of problems as well.

Hello all. I don't know about the chamber differences issue but I have a new Grendel build based on an AA 16'' stainless bbl,

BCM stripped upper, SOLGW stripped lower with an ALG QMS trigger. I also filled out the list with an VLTOR A5 RE, a geiselle gas block,

and a VLTOR flash hider. So I get out to the range to test the ladder I loaded up and at 28.0gr of 8208XBR under a Hornady 120gr AMAX in new PPU brass with CCI LRP

I popped 2 primers out of the 5 and none of the 5 pcs of brass will hold a primer any longer. The other 20pcs all show significant ejector swipes and no other popped primers.

I saw this thread and contacted the phone number and spoke with a Marta at PPU, this is the email she sent me. I hope to not be violating any rules, if I am please remove.

Good luck all.

Headspace issues due to many chamber sizes for 6.5G is the response I received from PPU USA.

Quoted:
Maybe PPU should stop trying to pin all this on the rifles (that had no issues with the old ammo) while some of their credibility is still intact.

Quoted:

almost looks like the "brass" is rubbing off near the extractor grove and on the mouth of the primer pocket.

probably just an optical illusion, or PPU is experimenting with lead cases...

Quoted:
I shot a box of this recalled ammo today and had one blown primer, several failures to extract (from a friends gun, everything ran in mine) and several other dangerous signs on the brass.

I guess I'll have to find a receipt and send this crap back in, it really is bad stuff.

ATTENTION USERS OF WOLF GOLD and Prvi Partizan 6.5 Grendel

My concerns about this ammunition started a couple months ago, while shooting with some friends a box of wolf gold was produced and was fired out of 2 rifles, both of which produced spent cases exhibiting excessive pressure signs; very flat primers and backed out primers. At the time I did not think much of it, I brought the brass home to reload, upon inspection the cases showed excessive case stretch at the base of the brass. The brass was discarded. (not a fan of the Large primer anyway)

Fast forward to a couple weeks ago, I was contacted by a user of one of the Satern group buy barrels. The user had the barrel in service since last spring with great success until the user reported piercing primers and brass that showed excessive pressure signs. I instructed the user to send the barrel back to me for inspection. The barrel, bolt and fire pin were all within specification in regards to head space and firing pin protrusion. The user also supplied 3 fired cases, Wolf gold manufactured by PPU (prvi partizan).

Out of spec ammunition suspected, I acquired some factory new PPU 110g fmj and the 120g HPBT. using the hornady headspace tool and the .35'' bushing both boxes and a box of factory Hornady Amax were measured. The results are scary enough for me to discontinue the use of this PPU ammunition due to excessive head space.

SAAMI published cartridge specification is 1.220-.007''  or 1.213 min.

Factory Hornady measures 1.210''-1.213'' At least they can get something right sort of, the shortest of them were only .002'' under. This of no concern or is it? We are under the min on a few. could this also be some of the high pressure signs some of been reporting sometimes?

However all of the PPU ammunition measured between 1.205'' and 1.208''. out of specification.
a quick web search finds this post over at http://www.predatormastersforums.com/forums/ubbthreads.php?ubb=showflat&Number=2848722&page=1   That shooter is lucky nothing worse happened, they blamed high temperatures, what they didn't do was measure this ammo!

Quoted:

That is what they are saying, I shot a older lot and 0 issues except for softer brass making it impossible to reload more than twice due to primer pockets opening up. The new lot I bought is now popping primers and is junk after 1 firing. The other weekend a guy next to me was having problems with his alexander arms and I helped him diagnose it, I saw this..http://i1062.photobucket.com/albums/t488/libilaw/121C6946-477C-481B-A275-A930590CB8B1_zpszw62j8fe.jpg
Same issues, never had a problem with other lots but this new lot has some serious problems

Quoted:
Black hills makes 6.5 G ammo? Is it discontinued, I don't see it on their website and a search came up blank?





The Black Hills 6.5 Grendel is only sold by Les Baer.  I still have two boxes which are loaded in Lapua cases with Sierra 123 grain Match Kings.  The last time I checked Les Baer's web site they still sold ammo but it was loaded using Hornady brass.  The boxes are marked Les Baer and not Black Hills.
