Headspace off of the belt, or the shoulder? How, why?

Which stock for an internal mag?

26" 1:10 barrel, or other?

Looking for .5 to 1 moa out to 800 yards.

I've built a few Savages with excellent results, how does the belt fit into headspacing the barrel?

Can an accurate 300 win mag be built in the same manner as .243, or a 308 etc?

Thanks, Matt.
