I am still happy with this purchase as it presents an opportunity for a custom shooter.
This is the throat.
That trench goes around about 1/6 of the throat.
This is typical of the last third of the barrel.
I shot some factory Remington Core Lokt and it was grouping about 2" at 100 yards. My #1 in 338WM can shoot right at 1" with factory ammo.
I can send it to Ruger and have them bring it back to original condition, or send it off to a barrel maker (Pac-Nor for one) and have them rebarrel it to another caliber. I would be more than happy with it back in its former glory in 7mm mag. I also think it would be really cool in another caliber in a fast twist, 22, 6mm, or 6.5mm something. I am not in a hurry to do anything with it at the moment.
