One of the great Ultra-Mag chamberings and rifles IMO. I found one over the summer on another forum that was owned by a guy who happened (it turned out) to live about 35 minutes from my house! I just got finished with the Area 419 brake install and some other minor gunsmithing on it. I used it this year to take a cow elk at about 400 yards using Berger Elite Hunter bullets. The only challenge has been finding brass to use to reload. I ended up buying 300 RUM brass and then forming it into 338 RUM which is very easily done.
