I like Stainless as well. I own a 700 SS 5R in .308 that is a laser. The H-S Precision stock that came with it was decent, but didn't fit my shooting hand well enough to make me feel like the rifle was an extension of me when I was shooting.
Owned a tupperware (plastic) stocked rifle or two. Shot them about 4-5 times at the range and realized that the groups, although fairly decent always shifted from one target to the other depending on what angle I was at, and where the pressure against the stock was coming from. Always found that I could shrink groups a bit more by switching to a good aftermarket stock and bedding it.
I think I just made a reply to your other post (if it was yours) about a 700P in 7mm RM. If you are dead set on a 7mm RUM, the Sendero SF II would be my first pick for a factory rig. The RUM is pretty ridiculously overbore therefore barrel life will be much shorter, but for a hunting rifle that will see 20-30 rounds over a year after sight-in and load development (if you handload) that is a moot point. Hope this helps.
