I have hunted but not taken and elk with a 300 savage. I have however taken 7 moose with the caliber and numerous black bears.
Outside of the teasing I get at camp when my fellow hunters see the size of the bullets it has been very effective.
I now use a 3006 as it offered extended range with more umph and better bullets ( out of the factory).
I only ever felt under gunned with a savage at ranges over 250 yards. I use federal 150 grain factory and the rifle will shoot MOA
