My stainless 308 Package Rifle shot sub MOA with cheap factory ammo. I like it well enough that I had the barrel cut to 22" and put it into a B&C BDL stock like this. My gunsmith sold me the bottom metal just before it became unobtainable. He also said that the chamber was bigger than a standard 308 chamber, and was probably a 7.62 NATO chamber.
I bought one and bolted it into a B&C ADL stock. Pretty decent rifle.
My riflesmith Bud told me that the current 700 actions he's barreled have been surprisingly true with very little runout.
That's what my gunsmith said. It's still consistently sub-MOA with a number of loads, but they're different loads than what it shot well when the barrel was 24" long.
I agree that Remington figured out the 700 a long time ago.
