Brownell's just sent me a notice. They have Federal 115 and 124gr 9mm in stock at $0.50/rd. Doesn't appear to be a limit.
Apologies to Kevin, but Ammoman has never been the cheapest supplier, HOWVER, I just got an email and they have bulk Federal 9mm 147gr, AE9FP, for $0.485 / rd. Nine cents LESS then Federal's price. Plus Federal has a 200 round limit per order.
