I think the options are too strict here. What about using it in support of other weapons? These options only seem to allow for primary weapon, never use, or tentative use without confidence.
I'll use it;
When rocks are plentiful.
I need to be silent.
I'm bored and want to do something.
I have the time to spare.
To tie what needs to be tied.
My primary weapon would probably be an atlatl, as I can actually make that compared to a bow. I own no guns nor have enough experience with them. for effective use in an outbreak.
We've got isolated pockets of people in suburban areas? Great! Slinger (note- this word is underlined in red

) friends to be made. Get a group, volley attacks at the zombies, relying on abundance of ammo and slung shots. Always make friends.
