I prefer not ordering numbered contours. Different barrel and stock makers mean different things with the same number which can lead to mismatches between barrel diameter and barrel channel in the stock. "remington sporter", etc are universal and if the barrel and stock makers use those, you're more likely to get compatible dimensions.
Remington lists their factory short action sporters around 7-1/4 pounds. With a slightly lighter stock, I think you can break under 7 pounds with a sporter, rather than mountain rifle, barrel contour.
Not all barrel makers will flute a factory sporter, most will flute a factory magnum (that's what a LVSF barrel is), but you might ask. Flutes on a small barrel like a factory sporter won't save much weight, but even a couple ounces might make the difference between hitting your weight or not.
You can save a little weight by going with ADL rather than BDL magazine setup.
