Yes you need a back-up, and then a back-up to your back-up, and then a back-up to your back-up's back-up, etc, etc.............
I'm with this guy. When I go out west hunting I take my 7mag for my primary gun, my 243 for a secondary gun, my 50ML for a third option, 223 for fun, 357, 40, and a 22 mag just for good measure. Some think I am over-prepared, until they see a critter and ask to borrow one of my guns.
