Ok I like the weatherby also, however, it is not best 30 cal magnum by a long shot. The only advantage it has over the 300 WSM is the ability to push the heavier bullets.
For example it was quoted that the writers weatherby runs the 168 Barnes TTSX at 3269 fps into a 1.5" group using 90 plus grains of powder. Well my 26" 300 WSM happens to run the same 168 TTSX at 3253 into .5 inches and in a much lighter short action gun using 60 plus grains of powder. That is measured over a Oehler 35 with 8ft screen spacing and multiple measurements so no fluke.
So basically same MV for 1/3rd less powder. Now thats efficiancy!
I shoot LR BR and have used both the 300 Weatherby and the 300 WSM. Both are great shooters and very close in accuracy and MV. We routinely run 210 JLK and Bergers at 2950-3000 fps in the WSM. Now the Weatherby will run them 3050-3100 tops.
Plus, mosty importantly I get 2-4x the barrel life in a WSM. Danny Brooks 2008 Shooter of the Year for 1k in IBS won with a WSM that had 4000 rounds in it at the end of the Nationals. NO other 30 cal magnum has ever done that. My first barrel had over 2600 rds before I pulled it and still winning. My weatherby barrels were toast at 1200 rounds max.
Once again the WSM is more efficiant cost wise in components and barrel life.
Is the 300 Weatherby the best magnum, not IMO but still very good.
