The 300 Wby may be great elk medicine to some. Certainly no questioning its effectiveness. However, more is not always more. It is not going to make any elk any more dead than countless other cartridges, while someone may shoot it fine, I don't see many shooting the big recoiling 300s better, and the package it typically comes in is certainly not a good elk rifle in my opinion. If I hunted from a truck or 4-wheeler, and ranges were going to be really long I'd consider it. Otherwise, a 308 win, 30-06 or many others in a lighter, easier carrying, easy shooting package would be my preference.
