I've had 2 300 WSM MT's (3 really, but the first went back to Kimber). Both shot sub moa with a wide variety of stuff. I've had 15 or 16 (losing track) Kimber MT's. All would shoot something moa, some would shoot a lot of things well.
The MT 8400 is a GREAT stock, and is the reason the round is so shootable in such a light rifle. The barrel is too light for the round, but it's still pretty shootable. I'm old enough I don't care to deal with that level of recoil anymore.
To me a 300 is all about 180's and that's all I ever shot game with in mine (I did play around with both the 200 NAB and NP though).
