If you already have a 7RM and a .375 Ruger, is there any point filling in the gap between them with a .338WM?

The 7RM has plenty of thump for most anything south of the 49th parallel, and most stuff above it. It is faster and flatter to longer ranges than .338WM.

If you want a little more kablooey than the RM may give, the .375 Ruger is more than sufficient for anything on this continent, and most anything on other continents. With a 20" barrel and open sights, it makes a nice, handy little piece.

Is there anything a .338WM would do that either of these wouldn't do just as well? A little bit longer-legged than the 3/8, a little bit of a bigger hammer than the 7mm. But does that matter in any practical way? Is there any scenario where if you had the big one and the little one to choose from, you'd rather have the one in the middle enough to be worth buying a rifle, glass, loading supplies and equipment, and taking the time to work up a good load or two when you could be spending your time and money shooting other stuff you already have?

The looney answer is obviously to buy one in stainless/polymer and one in blue walnut. A less-looney compromise would be to buy one in stainless and get a nicer stock for it. What do non-loonies think?
