I’d be surprised if the AWR was headspaced wrong to the point of not chambering a round. I doubt it will be a difficult fix. The 5R rifling on those barrels is really good according to a couple of friends who own them. You’ll have a nice rifle without much effort is my prediction.
Good score on the Kimber. I have a Hunter and absolutely love it. Mine is a very consistent 0.5-0.6 MOA rifle with a Hammer handloads.
Truth be told, if I had to choose one gun between my Remington Mountain Rifle and the Kimber Hunter, I’m not sure which way I would go. The Remmy would possibly end up looking for a new home.
The trigger on the Kimbers is really nice. I installed a Bix’n Andy on my Remington, which was a huge improvement over the factory trigger.
Good luck with your new additions.
