Dirtysteve;
I have to agree with Bambistew, the small difference is not worth it. also the ultra mag ammo is very high priced and hard to find at most stores. The 338 mag is hard to beat as it is, and the ammo will be around for the next 20 years, The ultra mag may go the way of the Dodo bird and not be on the market ten years from now.
