I am looking to purchase a new rifle. Currenently, I have a Marlin 30-30 but I would like to purchase a more powerful, but not too powerful, rifle. I was thinking maybe something like a .270 or .308 or 30-06 because they are mostly used in PA. But other guns like the 300 win mag or a win 338 mag I don't know much about. So if someone could tell me what guns are more powerful than others I'd appreciate it. Also, I mainly hunt whitetail but I would like a gun that I can use for bear and if I ever go on hunts out west. Thanks.
