This is why I would pick the .338 Winchester magnum over the Remington ultra magnum or the Weatherby magnum.

The .338 Winchester magnum is available in about two dozen different factory rifles, while the Weatherby and the Remington ultra are only available in a handful of pretty expensive rifles.

The .338 Winchester magnum also has a huge following in the elk hunting community, and there are many many many great elk hunting loads available in this caliber. There are nosler partitions, bear claws, fail safes, barnes x, grand slams, A frames, and a huge list of other bullets available to choose from when sighting your gun in. What if the two or three elk loads available didn't shoot well through your Remington ultra mag?

You will never meet a man alive that wouldn't list the .338 Winchester magnum as ideal for elk, moose, big bears, or almost any other big game for that matter. It is a time tested and field proven big game cartridge.

Now that you asked my opinion, and I won't get kicked in the nuts for giving it LOL, I am happy to share this information with you.

To go one step further, the 338 Win Mag is even available in one of the nicest semi auto rifles ever made, the Browning BAR!

If you have any other questions, please let me know!
