I'm just starting out hunting and haven't yet purchased a rifle. I only want to buy a single gun right now, but will likely hunt a number of ungulates with it over the next few years. What is a good single caliber for hunting deer, elk, moose, caribou, etc? What is the real-world application for different calibers (ie: why do some people like .338 and others 30-06, etc)?
Any information is greatly appreciated
Thank you so much
Cody
