Seems there is a hole in the distribution system where product is disappearing and no one seems too concerned to find where that hole is.
That hole is in the "Just in Time" inventory that every level of manufacturing from raw product to consumer retailers aspire to. Nobody wants inventory carrying costs, so there's no inventory.
Local Scheels gets ammo every weekday, prices it and puts it on the shelves, basically normal price with 1-3 box limits.
