I have read so many of these articles/reports, that the first thing I do is look at the bottom line. Almost all of them have the same tag line. The best caliber for anything in North America really isn't just one. Sure one caliber can be used, but for everything in North America what ever caliber you choose will be better for one sized game better than the other sizes. Regardless of what you hunt, the best caliber is what you can shoot the most accurately, using a caliber and bullet for the size animal you hunt, within your comfortable maximum shooting range. But the articles/reports have been a great help because for each report stating what is best I have a good excuse for a new rifle, so keep em coming.
