Walmart gets shipments EVERY NIGHT. (They don't ALWAYS get ammo, but they do most nights).
I call at 6:00 pm usually, ask for sporting goods, then ask what they are getting on the truck. Usually they tell me.
If the person is stubborn, call about 8:00 pm and they are stocking the shelves so you can ask again. I did this and got 750 rounds of 9mm the other day.
I call them daily, and call Big 5 every Friday morning at 10:30 am (they unload truck when they open at 10:00 am on Fridays).
Bass Pro in Manteca gets shipments sometime on the weekend.
Alquist Arms in Turlock gets shipments daily between 1pm-3pm of firearms (been looking for a glock 23, so i bug them often).
I know this is a little outside of ammo finds, but good info!
