I am an avid deer hunter and have been for many years. However, I have only hunted in Indiana where rifles are illegal to hunt with. Needless to say I have minimal knowledge about rifles. My question is I am looking for a well rounded rifle to use for deer, moose, sheep, and possibly bear. I was told a 300 win mag would do the trick but have also heard that a 7mm is better. I'm at a loss as to what rifle to get. I would hate to get this huge rifle specifically for big game then move away and never have another application for it. Any suggestions?
