I am sorta in your boat and have been doing it for a couple years now and don't plan to buy more for a good while. I categorized by...well category instead of use.
Handgun:Commander sized 1911. Used in an HD and CCW role currently.Had this before this since 2009.
Rifle:Bolt-Action .270 WIN. Hunting Only, Will take elk and black bear easily at distances Shotgun couldn't dream of. I feel comfortable shooting this at anything but Kodiak with the right load in the CONUS. Got this in 2010.
Shotgun:Weatherby PA-08 Pump 12 Gauge. This will do Birds, Small Game, Big Game, HD Got this in 2011.
Rimfire:Mossberg Plinkster .22LR. Small game and shoot for stupid cheap.
That is really all that I feel is NEEDED, the .22 is questionable as it's role is filled by the shotgun and its purely more economical for me to shoot rifle. The .270 rarely gets shot, the shotgun, .22, and handgun get shot most often. I am in the process of building an AR in 5.56/.223 to shoot centerfire rifle more affordably than the .270 WIN and I want something semi-auto centerfire for coyotes and in the back of my mind in case of a SHTF situation. I almost laugh at the people preparing hard-core for this scenario but so much is going on I figured I'd be more comfortable laughing while I prepare a little myself.
