Scott,
Oh man, 257 Wby is very cool.
As was mentioned, 264 Win Mag and 7mm Rem Mag brass can be used for 257 Wby with a single pass through a 257 Wby FL sizing die.
I have a stash of 7mm Rem Mag brass for just that reason.

Thanks guys! Placed a couple of bids. It's funny: I checked those sites before I posted and found lots of Bob product but no Bee product. I have 270Bee and 7 rem brass. Just like to keep correct head stamp when I can.
Jim - Going to be an interesting gun. It has 31" Douglas barrel. I wonder what velocity I'll get out of the 110 NAB. I wish there was a 120gr LRNAB!

Scott,
31" tube should make it a screamer!
Maybe one of the guys will run the numbers

These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
