Tracking ammo

How does everyone track how much ammo each character starts with or runs with? Or does no one bother with tracking it?

Thanks,

I never track it, unless as Barter.

"You are low/out of ammo" is a MC Move, make them buy, activate their crap's downside, make Apocalypse World seem real, announce future badness, &c.

Make sure it follows from the fiction.

Also, where do you get your ammo from? is a great question to ask PCs.

If absolutely everyone at the table things it's neat / add verisimilitude / are gun fetishists, then you could track every bullet if you wanted too. That personally sounds tedious to me.
