I would suggest a .308 or a .270 as they are usually much easier to find ammo for than 7mm08, which is a good round too, but can cost more than .308 also. To me, it always seemed like the 243/6mm Remington was outclassed by the 240Wby. The 7mm08 I had was outclssed by a .280, for sure 7mm Mag. But the 308 was "so close" to the 30-06 with 150-165s that it was just as good as a 30-06. This is with Factory loads, mind you.
