I have been consolidating calibers and stocking up on ammo. I have what I think is enough ammo but am wondering what type of ammo would be best for a SHTF scenario. I currently have about 80%FMJ and 20%JHP for each caliber. I have ran JHP through all my firearms so I know they will eat them. So, incase of a collapse in society, what type of ammo should I have? For a zombie attack? Should I start buying more JHP? Should I even care about over penetration in any type of SHTF?
