I have a #1B in 257Roberts with beautyfull wood. I bought it used and thought to turn it into a 257Wby. It is an easy conversion. But,But,But it is also super accurate the way it is set up. It sits in the Vault and I never used it once on game since I got a Handi custom 257R which is also a tack driver and about 1.5lbs lighter. That is one of my guns I take hunting most of the time.
Now since I build that #1B in 6.5x284 I guess the 257R will stay as is. But make no mistake the 257Wby is one heck of a cartridge. I had a MK V Wby rifle in 257Wby a long time ago and good bullets were not easy to come by. Bullets would either blow up or pass clean through the game. Now a days bullets are no trouble anymore.
But be aware that the 257Wby demands the best bullets you can get.
