Re: 257 Weatherby Brass
If you're not concerned about it being correct headstamp I have some new Norma and Weatherby 270wby brass that is collecting dust. Make you a heck of deal on some or all of it if your interested. I think I even have a bunch of 1 and 2 fired 270wby brass that I'll throw in with it.
257, 270 and 7mm are all the same so all you have to do is run it threw your FL die and you'll be good to go.
