That's all true, but let me mention another option. The old .30-30 is still a good all around caliber and ammo is available almost anywhere ammo is sold. Also, anybody with a press, dies, and components can reload fired .30-30 brass and make decent ammo.
A 16" or 20" barrel .30-30 lever action carbine is a handy and easy to shoot shoulder arm for either survival hunting or home/business defense. Winchester is out of business, but there are plenty of both new and used mod 94 .30-30s still on gun store racks, not to mention Marlin lever guns and the new Mossberg lever carbine in the same chambering. They aren't glamor gals and they aren't chambered for newfangled gee-whiz cartridges, but they still get the job done as they have for the last 100 plus years.
