Guns or ammunition? I don't think anyone is currently chambering for it in a factory offering as far as rifles go. It is actually one of the few types of factory ammo you can find on the shelves here. I have seen a bunch in 2-3 different shops lately. I have a rifle that PacNor barreled and chambered for me that is a tack driver. I have enough brass and components to keep me shooting quite a while with it.
