Since I am having a fairly difficult time finding brass for my 257 Weatherby Magnum, what would be the challenges of just buying some Lapua 375 H&H brass and running it through a full length sizing die? I know that I would have to trim first, but what else would need to be done?
Haven’t done this one myself, but that seems like it’d be an uphill battle. You’d have to neck turn every single piece going from such a large caliber to a relatively small one.
That’s what I thought, but wanted to see for sure
