The major difference between the Savage and Remington WSM's that is not fixable is the Remington action is shorter than the Savage.
The Savage is a 7 WSM and I can seat the bullets to touch the lands and still fit in the magazine. The Remington is a 270 WSM and I can not seat the bullets out far enough to touch and still have them fit in the magazine.
The Savage out shoots the Remington and is considerably cheaper.
