7mm Mag and .308 are so versatile. A large array of small and large bullet grain sizes available to them, more than other calibers you listed. Both will reach-out beyond 300 yards and I personally would choose the 7mm Mag.
Fourteen years ago the 7mm was the new rage with shoppers looking for hunting rifles. I chose a .270 back then and today feel I made the wrong choice. With the 7mm, I can load a 110 grain bullet one day for yotes and 175 grain the next day for elk. The .308 also offers a wide range of bullet sizes.
