Caramel.......are you sure you're ready to stray from your 308 "comfort zone", this is a huge step up, maybe you should have gone '06 then 7 mag then maybe 264 WM..........to jump right from 308 to 257 Wby, not sure you'll suvive the "culture shock"............Rainbows to lazer beams, I don't know.......LOL
Caramel, you must be made aware of one downside to the 257 Bee, it is a trophy hunters cartridge. You will NOT be able to eat up to the hole as you can with a 308. I have taken 3 caribou with it and elected for shoulder shots on all three, there was absolutely nothing left edible from the ears to the last rib. The blood shock and bruising was extensive, literally from 1/2 way up the neck to the last rib was completely destroyed. Stick to rib shots if you intend to eat more than 1/2 your animal. It is one of the most devstating cartridges I have ever seen, except possibly the 300 RUM with 150-165 gn bullets like my kid uses.
