I know this will sound strange on an all out survival Rifle Post, but in adition to what ever firearm you choose, a set of traps, and a Compound Bow of some type would be good to add to your survival gear. To eat you may need small game that you could catch with the traps, Quietly, and ofcourse the Bow would serve many purposes. You probably wont alwayse want to make a loud boom to let everyone know where you are.
