RE: Are we overgunned? Was Jack O'Connor right?
Kodiakhuntmaster hit the nail on the head, in that some folks want something more "suited" to the game they hunt. Of the deer that I've shot, I could have taken them all with a .30-30, cleanly. I used a .30-06 on all but one, and a .50 ML was the weapon of choice on the last one. Did I feel "overgunned?" Well, on a couple of the deer shot with my '06, yes. Did it stop me from using one? No.
For the type of woods hunting that I do, I feel that a magnum is a bit much. Then again, it ain't me shooting the magnum. To each their own, I guess.
