I don't know where your custom Rem LSS Mtn rifle will come in weight wise but the factory version is about 6 1/2 Lbs. I can't even begin to imagine the recoil of a 350 Win Mag in a 6 1/2 Lb Mtn rifle! Hope you're not recoil sensitive.
I agree with Vapodog......go with the 7mm-08. I've got one in Rem 700 Mtn LSS and just love it. It's a real pleasure to shoot withlight recoil and it's very accurate as well.Put a scope with a bullet drop compensating reticle on it and trajectory becomes a mute point. I put a Burris 3-9x40 w Ballistic Plex reticle on mine.
Here's a pic of mine.
