My "standard" rifle test target was close to 1 MOA. I get 1.5 MOA with cheap hunting ammo, first shot generally is X-ring with a cold barrel. I think I can get <1 MOA with carefully chosen ammo, but it's my hunting rifle, not a range toy, so I don't care. Dead on with a close-to-center followup shot is all the performance I need from it, so if I can get that with Wal-Mart Winchester soft points, I'm not going to dink with it.
I have a walnut-stocked Vanguard Sporter in .30-06. I like it a lot. Fits and feels great. Trigger needed adjustment, but that was just a screwdriver and wrench job; the manual tells you how. Snap caps are your friend.
The Sub-MOA barreled actions are from the same lot, from what I've read in a review when they first came out. I believe Weatherby just selects the barreled actions that shoot the best on the test target, then stick them in the fancy pillar-bedded aramid/fiberglass stock. (EDIT: I didn't know it was a Bell and Carlson. That's worth a little money; those things aren't cheap if you want to get one aftermarket!)
Remember, though, if you get the sporter weight barrel, it'll heat up and lose some accuracy after a few shots, unless you let it cool. Hunting rifles are made to carry comfortably and point well, not to keep their barrels cool for a long time.
You can get the same gun, in a few calibers only, with a heavy barrel (Varmint Special and Sub-MOA Varmint). It's not THAT heavy, just a step up from a sporter.
