Weatherby brass resize 416 to 460?

[NW42]

I’m needing a box or two of 460 wby brass and I’ve noticed for whatever reason 416 brass is noticeable cheaper than 460 brass even though it’s the same case. Has anyone had any experience in sizing 416 to 460? I’d like to try but considering the overall price of the brass I’d hate to end up with a bunch of split necks.

Anneal it and split up the expansion with two mandrels.
I do that with 338 to 375.
