Another same-ol'-same-ol' bear gun thread arguing about another inadequate caliber/gun combination.
Here's a clue. If your first shot doesn't stop or at least deter an attacking bear, you aren't
gonna outrun one.
If you can't take the proper gun with you for protection, you need to stay out of the woods. Can't afford the proper gun? Save your money until you can, or take the chance of ending up as bear scat.
