It will work fine. When considering such a whimpy cartridge as the 7mm-08, remember it is ballistically equal to the 7x57. Also remember that Karamojo Bell killed elephants with his whimpy 7x57. Remember the 7mm Remington Magnum has an amazing 200 fps advantage over the 7mm-08.

Now, the rifle. Which one fits you best? Thats the one you should buy.
