What barrel would you choose and why

[eaglesnester]

I have a P-17 Remington converted to 308 Norma Mag. Barrel is getting on and heavly pitted from neglect before I became its new owner. Thinking about doing something with it by rebarreling. I have a Remington 700 30/06, 300 Weatherby, 22/250, and a 375H&H. What caliber would you choose to make this fine old but abused rifle into and why? Have been considering the 7 em em.
