Who would want to lay siege to my apartment?
And if we're talking about the "Z" word, I don't have enough skull beef to interest an army of them, just ask the fiancee
Anyhoo, I usually don't have more than a couple hundred rounds of 9mm & .45 at any given time, and don't yet own my own shotgun or rifle.
Why would you not be able to leave? Are you shooting at things/people outside? If you're not shooting you won't need much ammo
If you are, couple thousand for each caliber maybe? I'm not a great shot, might need all of 'em.
And just in case: In before the lock
