If it was my '03, and I have a couple of them, I'd probably go .280 or .280 AI to scratch a 7mm itch.
For a hunting rifle, the short fat rounds really offers no advantage and the longer ones, especially the AI version, will shoot faster.
In fact, the .280 AI is pretty close to the 7RM and more efficient. If I didn't already have a great 7RM, I'd be looking at one.
