a 25 round magazine of 22 rimfire would a bettr defense than a bow.
Better how?
With a quiet can maybe I'd agree. But I have little faith in a .22 saving my life and would never trust it to save my family. In the scenario of topic, quiet is good. Anyone who has something they are willing to defend, has something the rest of the mob will want. Be it food, supplies, Meds, etc. A bow is very lethal, nearly silent, and I have plenty of other options if it isn't sufficient.
The less attention you draw the better. If I have to get noisy, I'll choose something way more effective.
