If it ever gets to the point of survival like you guys are talking about, I'm glad I won't have to choose just one weapon. Myself and my family(all the way down to the 10 year old) will be packing. If I did have to choose one for long term survival, I think I would aggree with Pavomesa. My Marlin bolt action with 17 in the tube would provide well for my family. Second choice would be my .223.
