Have you tried different ammo?

[G woody]

Did you use the same scope of different scopes ?

How were the groups fired ? ...Bipod ?... Benched & bagged ?

I also wonder if "something" is making contact with the barrels gas block.

Some of the shots are "off" enough to make me wanna look for contact.

I will check for contact tomorrow and see if something is touching. The rifles have been fired off bipod prone and bench rest with bags.

Have you tried different ammo?

Yes we went through every major production match ammo with both 168gr and 175gr

Did you use the same scope of different scopes ?

Both guns have the same make/model of scope. We did swap out mounts to try and rule that out.

OK, so you tried a bunch of factory ammo, but what about handloads tested and optimized for each rifle itself? Time consuming, I know, but sometimes it's really the difference between a rifle you think is crap and one that just needs what it needs which then it beats the pants off of everything else.

I would expect OBRs to perform better than the targets we are being shown. Having one of them not consistently meet MOA is one thing, but for eight of them to do this is something else entirely.

Have you contacted LaRue yet to get their opinion? What ammo did they use for their test target?

I agree, there is some commonality among those guns or the circumstances. Are all the guns the same 'batch?' Configured the same and made at the same time?
