Ditto. Been looking for months. None in stock. Interesting....as I burped a ton of brass into Ackley tooling around all over Las Cruces. Quite a few bunnies S of the checkpoint
Have you checked local shops? A store local to me has kept a steady supply of Lapua .223 brass (i haven't been there in a few weeks but they have had some for months).
The last time I was looking for .223 Lapua brass and couldn't find any I ended up buying a case of loaded Lapua 55gr in a wooden crate from a local gun store. After factoring in the price and availability of primers, powder and bullets I figured I came out ahead on the brass. Just pick it up and reload it as I use up the case.
