I see no problem with carrying the 22 in the BOB. I would also have other firearms though. If I have to bug out, I will be taking my family and they will all be carrying something and each will be carrying a weapon. As we go and scenarios change, we will adjust accordingly. Starting out, I would rather have too much than not enough. If it gets to be too much, we will lighten the loads as we go. Once all of our supplies dwindle and we have narrowed everything down to bare necessities, well, we'll still have our firearms and TacOps change.
