Indiana is considering allowing rifles for deer hunting. I've lived here my entire life, and have only used a shotgun for deer, so I don't own any rifle larger that a .22. If this goes through, I now have a good excuse to buy a rifle.

My question is, what caliber rifle would you recommend? I'd like something that would be multi-use that I could use if I ever go hunting for some other species of big game or het the chance to hunt somewhere that is a lot more open country that Indiana is.
