I've been interested in picking up a hunting rifle lately. I would be hunting deer at the biggest. But there are black bears in the areas I would hunt in, so I would also like the rifle to be powerful enough to kill or scare off a bear encase I encounter one on a hunting trip. I really don't know too much about the different types of rifles and stuff, so when you recommend a gun, if you could give a little info on it, I would appreciate it. I would be willing to spend around 500$ or so at the most, unless I can find a bad ass gun that costs a little more.
