Dan Lilja has a good chart here:
Lilja Precision Rifle Barrels - Caliber and Twist Rates
A note on free floating the barrel, shoot it first. If it shoots good, leave it alone.
Not sure about the SPS, but Remington 700s generally have a pressure point on the barrel at the front end of the stock. I have heard the SPS stock is a little flexible, so if you float the barrel, the stock can flex and make an inconsistent pressure point on the barrel, rather the the consistent factory one.
In other words, make sure you have a problem before you fix it, and make sure you don't create a new problem when you do fix it.

One of the reason I am buying the Varmint version as oppose to the other more pricey versions that have "Tactical" or "Police" added (incl. an upgrade stock) to the 700 SPS model name is that I don't think it's going to make a big difference to me (not in competition) whether the thing shoots 1.5 MOA or .5 MOA. Maybe as I grow with the rifle I'll change it up, but for now the plain one will be just fine. I recall reading on snipercentral that the plastic stock of the SPS does deform onto the barrel when resting the stock on something, but that the accuracy suffered minimally, maybe a difference of .5-.7 MOA. If I can shoot 1.5 MOA or better with the unmodified rifle, I'll be happy for $560
As for twist, you can get a Remington in 308 with 1/10 twist. Some of the 20" and stainless barrels are 1/10. I'm no going to be sniping anyone or joining competition, so the cheapo ammo will work just fine then. 140 gr to 180 gr...cool. I'll watch for ammo in that range.
How about a good but cheap scope? How powerful a scope? I think there's a 600 yd range not to far from me, and that's about as long as I'll probably shoot.
