I have a few of the guns you mention. I like them all and I would use anyone of them as a defensive weapon for my home if I had to make long shots. However last year I read an gun mag article about a bugout rifle. He recommended one of the Remington pump rifles in .308. THe rational was that it would be good for hunting and could be used to good effect against other targets but also that you wanted be looking to get into any protracted firefights like the army so a pump would be ok. I also read a Ayoob article where he sang the praises of a SA M14 clone. Powerful cartridge and good long range capibilty. I know .223 is what the service uses but I think there are definitly some of them that would like to have something bigger.
