Hmm sounds like a split vote. My only hangup with the 257 is Norma Brass and spending double the amount that normal brass costs . Although in the long run if the gun is a shooter and it will be(remington custom ) not a big deal. I have also considered building a 257 WSM and using necked down 270WSM brass.
If you are going to go to the trouble of working up the brass, why not make a 25 WSSM? It would be small light, pack the punch of the 25-06. I think the 25 WSSM is probably the best WSSM at least from what I have read (I haven't shot one). 25-06 velocity and weights in an action shorter than a short action (.308, etc.). Seems like a great deer round. I'm too cheap to buy one when a box of bullets is so expensive, but if you handload anyway and you have to work up brass for the 257 Weatherby anyway, why not just go 25 WSSM?
