Well, for accuracy testing, I swapped out the scope in favor of a 4.5-14x Leupold, and took it to the range with some factory loaded 150 grain Remington ammo. Here's the first group at 300 yards:
Not stellar, but it shows me that the rifle has potential. Am looking forward to working up some precision handloads for it, and likely using it for mule deer hunting this fall. Will update as I work up some better shooting loads. I'd like to cut this down to a 3" group at 300 yards, or better.
I'm so enthused about this rifle that I could see hunting with a small battery of single shots:
A varminter in .204
A light-recoiling deer rifle, like a .25-06 or a 7x57
This 7mm Rem mag for longish range mule deer, elk and maybe black bear
Maybe a bigger bore for fun, a .45/70 or ???
