I could find love in my heart for a M7 in 300 WSM but likely not in stock configuration due to feeding issues and COAL limits.
I will say, I love my .358 M7 and Hornady is making .358 brass!
To expand upon the advice to buy a bare action from Bud's, that's a great way to go if you want to have exactly what you want. Lead time for premium barrels and stocks is ~ 6 months so you could have it by hunting season if you get rolling soon.
