I recently purchased a Ballistic Advantage 20" 6.5 Creedmoor SS Barrel and am wondering if anyone else has had similar issues.
Issue #1 - Chamber too tight (see pics)
Chamber will not safely allow a round to be inserted and seated without excessive force. I had to slingshot the bolt to slam it into battery to seat a round in order to fire it to test accuracy. (yes I know this is not safe) When dropped into the barrel the casings sits out over 1/8 inch. I tried 3 different types of ammo to rule out the ammo as I was hoping that was the cause but it's positively the barrel. I had to mortar the casings out. The barrel has since been removed to send back. I inserted a round backwards just to see if it was the area of the casing nearest the primer but it is actually the throat that is out of spec. (Ammo = Hornady 143 ELD-x, Federal AE 140gr OTM, Hornady 120gr Amax)
Issue #2 - Crush washer will not sit against the shoulder. The material in that area was not relieved after the threads. Tech support told me that I had installed the crush washer backwards. Really???
My dealings so far with BA's tech support have been very poor to say the least. That's another story...
Anyhow curious to see if anyone else has had similar issues and if so what happened. This barrel is from a very recent batch that a major distributor currently has in stock (not a public distributor, dealer only) so others might get these barrels as well. But BA does not seem to be concerned about it.
Here are some photos.
