A good m-14 gunsmith located in Canada...

My experience with the black feather has taught me that if you follow the instructions that come with the chassis you will have better "out of the box" results.

I have also found (and this is not just me) that cheap federal blue box 150gr ammo is "the most reliable" factory ammo to benchmark accuracy in the M-14 platform, or any 308 rifle.

My advice, install the rifle into the black feather, tension the barrel as described. Shoot a minimum of 10 rounds sighting it in and then once the rifle is warm and zero'd, shoot a 10 round group "for score". See how that is.

At that point "fiddle" with the barrel tension (more not less). Remember to shoot a minimum of 10 rounds to settle the rifle into the chassis after every adjustment before "shooting for score".

Once you find a tension you can live with, or re-settle tension to where the groups were tightest.

Do load development from there.

Good luck!
 
I called Tac Ord but they said they have no time before at least March. What I will do is follow the recommendations of some people here and have the present barrel recrowned. Then I will validate my optics. If this still doesn't work I will seek other options.

you can't recrown a chrome lined barrel, I'm assuming it's a norc.
 
It is sitting flush, but no I have otherwise not attempted to tweak it. For the simple reason that, as playing with loads, these are refinements that I work once the gun is steady. However bad it is. Know what I mean? I feel like there is fundamentally something odd and I will find it. Then I will spend winter effin around details for the pure fun of it.

But did you set the barrel tension to the "default" amount as described in the instructions? Just trying to help rule out the obvious things first.
