Pass on this. You don't want a 20 inch barrel for long range work if you can avoid it, 24 or 26 is better when you have to go out to 1k.
The stock may be a McMillan, but you can get a McMillan stock for a Savage.
The FN Classic action has a very slow lock time compared to a Savage. It may win on stiffness in the vertical plane, but I'm not sure about that. The Classic M70 action disappeared from serious competitions by the early 60's internationally, but it held on a bit longer locally because the USMC was often too cheap to replace the ones they had (they just kept rebuilding them).
Machine guns are awesome until you have to carry one.
