have recovered MANY hundreds of rds of 223, count on that. half of 86 rds of 223, half of 200 rds of subsonic 22lr, that's a LOT of dead men, to expect NONE of them to have been carrying 223. Over half of them are going to be carrying .22lr, after the first few weeks after shtf, anyway. The ones who havent wised up and learned to have SOME sort of .22 will be long since dead. Most of the living, after a few months of shtf, will have some sort of silenced firearm, too. They will HAVE to, that's all, or they'll be numbered among the dead.
