The 30-30 is a great rifle and with well placed shots can bring down just about any animal . As far as SHTF I always figured the most important thing was to have enough ammo on hand . I was in the military and was never impressed by the spray as many bullets as you can and hope to hit something routine . I go for one shot one kill so any rifle will work for that . I like big bore rifles for the penetration factor if you get my drift , not to mention in a crowd God knows how many bodies it will go through before stopping . Theres a lot to be said for big heavy lead in certain situations . Remember the important thing is Ammo , Accuracy and Ammo .
