from previous posts i like Lepisosteus platyrhincus idea for the 22. i had not thought of the possibility if that. the 22 round is small, but powerful enough to penetrate the skull, but NOT enough to go all the way through a head. therefore the round would be like a bouncy ball in a small room and continue to bounce around the cranium until its energy was gone. a very effective weapon now that its been mentioned. it slipped my mind. i have 3 btw.
Yeah some attack dogs could easily defend you or handle some zombies while you reload. That is if it goes according to the good zombie movies and the zombies dont like dogs...
