The 25-06 is one of the better deer calibers out there and will do everything the 243 will do and much more. It would be a good choice. I have one in the Ruger bolt action. It has worked very well for me on the biggest Mulies. It will work for elk as well however I would move up to the 6.5's and 270 and up for an elk rifles.
