AR-Stoner 6.5 Grendel barrel short chambered.

[Sputnik]

I waited for one year to finally get my 18" AR-Stoner 6.5 Grendel barrel. First thing that I did was to check the head space and that was OK. I checked the cartridge overall length for a 123 grain A-Max bullet and the OAL was only 2.236". Since factory A-Max cartridges averaged out to slightly over 2.25", I did not want to have my bullets forced into the barrels lands. I sent that one back and they sent out a new one. The new one has an OAL of 2.246" which is only slightly better. I figure that I can safely fire the factory Wolf Gold 6.5 Grendel and any A-Max reloads that I load to around 2.23" Should I send this barrel back too? Hopefully, the 2 Lilja barrels that I ordered will have the proper chamber and I will not have to go through this bull. Anyone else having this experience with their AR-Stoner Grendel barrels?

Since you got it so recently, I am wondering if that was the run that Satern made that also produced the Group Liberty buy barrels. If so, Forum members may have that issue as well on their Liberty barrels.
