RE: 30-06 Jack of all trades, Master of None.
To each their own. I do like it. Don't know that it is the best caliber for anything as there are several calibers that are good for most animals. It is a good general round for us mere mortals who may not have a gun safe full of selections. I've killed 10 elk. One with a .308, one with a 30-30, and the rest with the 06 (Winchester xp2, 165 grains--there may be better bullets but this one is the most accurate out of my barrel and has had devestaing effects on any elk, deer, or antelope I've shot from ranges of 60 yrds to 250 yards). I've seen plenty of elk killed with 300 mags, .270s, and a couple with .243s and 25-06. I expect that shot placement, an appropriate bullet,andreasonable ranges for the performance of the cartridge and the abilities of the shooter really are more important than the caliber (in most cases).
