This actually happened to me. I grabbed my go to concealment rig, my M44 Mosin Nagant loaded with 240 grn Gold Dots.
With the bayonet extended I was able to kill 254 snakes, 412 regular bears, 232 zombie bears, and a boxcar full of feral dogs....
By then I had to reload and used the rounds I had packed in my tactical boot concealment rig and walked out alive, with my MRE's and water purification kit, all packed neatly in my bug out trailer.
