Based on your screen name I'm guessing you have a 300WSM. Load it with some of the better 200-215 gr bullets and it'll do anything the 338 will do with 200-225 gr bullets.
The 338 will look better on paper at the muzzle, but you can kill an elk at close range with a 30-30. Beyond 200 yards or so the better BC's of the 30's will translate into more speed and energy than a 338.
I can see an advantage if you move up to 250-275 gr bullets, but will you ever hunt anything where that is needed.
