I've been doing some thinking about this subject (yes, my head hurts)!
I am more convinced than ever that the NEF Handi-Rifle would be the way to go.
Start out by ordering one in one of the "high-intensity" cartridges (.243 Win, .270 Win, .280 Rem, .308 Win, or .30-06).
Once, you have the Handi in one of those calibers, you can have it fit with any of the above calibers plus several "low-intensity" cartridges (like .22 Hornet, .223, .30-30, .357 Mag, .44 Mag, .45-70) or any shotgun from .410 to 12ga. They even make a barrel for .45Colt/.410.
The complete rifle costs about $225-250. Additional rifle/pistol caliber barrel is about $75-95 and each additional shotgun bbl. runs about $45-65.
NEF also makes a .22LR version which is available only as a complete rifle that costs less than an extra Contender barrel in .22LR.
I have both a TC Contender and the Handi- Rifle. The Contender is really a thing of beauty, but is about twice as expensive as the Handi-Rifle.
The Contender has the advantage of handling .22LR barrels (at about $225) and can be transformed to a long barreled pistol. But the Contender is not available in any of the above "high-intensity" chamberings and is only available in .410 as a shotgun.
My Contender in .223 will shoot sub-MOA. I've only done limited testing of my NEF Handi in the same caliber, but with load developement, it should shoot as well.
I love my Contender and will never part with it. It is truly a thing of beauty and litteraly screams "QUALITY"! But when it comes to "most bang for the buck" and and most flexibility, the NEF Handi is my choice!
