The issue will not be with the steel case ammo, It will be with the chamber in the rifle. The Grendel is now a SAAMI cartridge or will be very soon. And I must assume that the Wolf ammo is designed to match this chamber.

BUT, the Grendel is a 10 year + cartridge design and has changed several times. in the last three years Factory produced ammunition was found to be too long for some of the chambers. This required a modification to the individual chamber. Prople threw blame at every side but actually it was just the maturation of the cartridge.

Things get better with time and we just have  to deal with it.

The first production run of the 6.5 had a straight throat and was designed for a single weight hand loaded ammo.

Things change.

If something does not work don't look for someone to blame...Go Fix it.

Grendel has been SAAMI for a while now.

Grendel chamber has not changed at all.  The Grendel chamber that was introduced by AA is the same today as it was then.  Several other people not associated officially with the Grendel have made their own chambers, and call them 6.5 this or that, many with the intent of being able to run factory Grendel ammo, and many have been found lacking, especially when they start making the neck dimensions tighter...to make theirs more "accurate".  Crazy thing is that AA allowed use of the Grendel chamber/reamer pattern all along FOR FREE, as long as barrel-makers promised to hold to that standard so we wouldn't have these problems.  

Yes, the Tula ammo marketed by Wolf is meant to run, tested in, and labeled 6.5 Grendel.  I doubt it will run in tighter necked chambers, let alone feed in many of them.

AA tested all these chamber designs, and settled on one.  What we have now is shop after shop re-testing or adopting lesser chamber designs for some unknown and irrational reason, then calling them "better", or we're "doing it right this time", and the customer gets screwed.  It makes no sense at all, especially since Grendel is SAAMI approved, and no licensing is needed.  Simply crazy.

Just make Grendel chambered barrels, and keep the standard so customers don't have to worry about it.  How hard is that?

The above post is spot on!  A little knowledge based in FACT goes a long way.  It's amazing how much unfounded hearsay is accepted as truth about this cartridge.

So I come to you for a refund when the steel cased stuff doesn't shoot 1/2 MOA in my rifle right?  

I'm glad that the steel cased ammo is going to be made by Barnaul.  They've always had better ammo than whoever Wolf had make their previous stuff.

From the man himself.

Thanks for the info.

I don't know about that, the PRVI brass Grendel MPT round is a pretty doggone good round for the price!

I'm all for cheap ammo but if it won't run in a 264 chamber, it isn't going to be a deal killer for me. I've never ran lacquer coated ammo in my ARs and don't plan to. Lacquer ammo is for AKs.

Don't let the cat out of the bag to my AR's.  They eat the stuff like it's candy.

Sorry I should have specified.  I was talking about Wolf's older steel-cased ammo (.223 and 7.62x39, .45acp etc.)  I've had issues with it being underpowered before, but never with barnaul.

The Wolf Gold line (privi) has been good to go in my experience, across all calibers I've shot.   Save for 1 or 2 fliers in a 10-shot group the 120 MPT is about 1MOA in my rifle.
