Re barrel and re chamber to a 6mm/06
The action is most likely a short action and the bolt face would be too small on his Ruger Hawkeye in .243win. Would need a long action to make the jump to the 6mm-06.
If you're just wanting something different get acquainted with reloading and experiment with load and bullet development for the 243win. Reloading will unlock the potential you already own in that Ruger. When you have shot the throat out with a ton of hot rounds have the chamber reset and rechambered in 243AI. or better yet just get a custom barrel in 1:8 twist in 243AI so you can take advantage of some of the heavier bullets in the 100 to 115 range.
Have fun.
