Although I have owned a couple of renditions of both chamberings in the past, I have neither at present, and no intentions of buying one. That being said, I picked the 300 Win Mag, simply because the difference in performance is not enough to matter, and the Weatherby rifles have always left me cold. Too Gaudy, the stock design is just a bit on the radical side. The cases are expensive, and the recoil is greater for little real gain. Personally, I prefer the 308 Norma Mag, or the 300 WSM. [Or if it must be long...the 300 H&H. Regards, Eagleye.
