If you can buy the Rem. or Win. .308 brass at Cabela's right now, do it. BUT I would bet they are out of stock like every online store.
Last few I got was from Mid-South before the election and haven't seen them again since.
Nosler brass is a better case and if you want new, right now, it will probably be all you can find. Other than that, keep an eye open for once fired brass. It's mighty scarce right now as well.
Good luck!
