I disagree on the suggestion for a Compact Hunter's Edge for the 7mmRM. The fore end on that stock is very slim. Not sure whose #3 or #4 contour you are referring to. I took a factory sporter, chopped it to 20" and stuffed it in the compact edge....there isn't much room for any more barrel contour in my opinion so #4 may be pushing it.
If you can obtain a Legend, go for it. Otherwise, I would recommend the Supergrade pattern for both builds. I built a M70 .264WM with a #2 Pac Nor and a Supergrade edge and think it turned out about perfect.
In case it matters, here are the final weights on two samples I have on hand:
Compact Hunters Edge, 13.25" LOP, 1pc bottom metal inlet, 1/2" Decelerator pad: 22.6oz
Supergrade Edge, 13.50" LOP, 1pc bottom metal inlet, 1" Decelerator pad: 26.9oz
