In light humor, I suggest the following...
Realistically, since you can only shoot one firearm at a time, you don't even need ten. Here's my suggested list.
Ma Duece (M-2) Browning Machinegun, tripod mounted or with turret ring for vehicle. Why, with the mighty .50 caliber bullet, you can take down any game from antelope to Elephant. Scoped, it can be used effectively at 1,200 yards (face it, it takes practice and skill to reach out to 2,500 like Hathcock did). Why, the M-2 is so good, you can even taken on a charging herd of Cape Buffalo. Little wonder that this ancient weapon is still seen atop of today's AFVs. Heaven forbid some Abrams or Bradley being scratched by a mere Rhino. The insurance company simply won't pay up for a new paint job.
Well, even though the 50 cal is an excellant bullet, admittedly it's a mite too big for some game like squirrel or rabbit. Vaporization leaves little for the dinner table and your wife's opinion of you as a hunter will greatly diminish. Therefore, the humble Ruger 10/22 is called upon as a secondary arm in your battery. Dependable, sturdy and spare barrels are really inexpensive. Why, thanks to the cottage industry which supports this gun and all those after market barrels out there, there's plenty of factory barrels out there which you can pick up cheap!
Since the Europeans think we're savages to resort to such weapons for defense, we might as well live up to their expectation and no battery would be complete without that most barbarous of weapons, the sawed off shotgun. Of course ours will have to be pump action with side saddle. With different loads and barrels, the shotgun versatility is unlimited. No need to stay with factory loads. If you reload, you can go with that most traditional of our French-Indian and Civil War loads: buck 'n ball. In a pinch, you can even stuff glass and soft iron nails in those shells. Little wonder those homeless folks secretly move around at night picking up glass bottles.
Fourth and final firearms is in the handgun category. A good long barrel (minimum 6") revolver in .38/.357 should fit the bill nicely. Simple, easy to use and no magazines to stock up on. It's a good caliber with sufficient energy and its long barrel can be used to roast game on. You can even use it to "pistol whip" folks but remember FitzGerald's advice in his book Shooting, don't strike with the barrel as you can tweak it but rather with the cylinder (and against the way it opens from the frame).
