I have owned my 300 whby for 6 years now and have killed 5 elk with it. All the animals where one shot kills from ranges of 80 yds to 328 yds. I use a 180 grain weatherby factory barnes x bullet. The ballastics for this combo are fantastic. It is a very flat shooting gun for a magnum rifle that also delievers good down range energy.
You wouldnt go wrong with owning that gun.
The 300 Weatherby definitely has the edge for the type of hunting you indicate. Your effective range will be further with it than the 338 win mag, and it is still going to do just fine on moose at closer ranges.
If you shoot it well, there's not much you can't do with it on this continent.
First make sure your gun is safe, remove the bolt and clean your barrel from the chamber to the end of muzzle. Clean the barrel using butchers bore shine until a patch comes out white. Run a total of 5 separate patches soaked with denatured alcohol through the bore and let dry for 30 minutes. Insert a cleaning rod with a jag and a dry patch into the neck of the chamber. Make sure it will stay there through the next process. Now using another cleaning rod, install a patch that has been coated...
