i just have had a 257 Creedmoor built with a 7 1/2 twist shoots great now with the custom dies, i also have 2 new 257 Roberts with a 7 1/2 twist barrels all 3 are Brux S.S. barrels the 30 Rem.Express that i had chambered 257 Roberts 71/2 twist barrel shoots excellent, the other one is a real nice Mauser i had rebarreled in a 257 Roberts 7 1/2 twist Brux barrel for my daughter but this rifle is waiting for me to pick up ,but since i had this back surgery it will be a while before i pick up this mauser 257 W. Mag.. i am thinking and wondering about building another 257 Weatherby mag. chambered ? looks like the best way is to buy a used Weatherby Mark 5 accumark rifle and rebarrel with a 257 Weatherby Mag. 7 1/2 twist Brux barrel for the best accuracy and cheaper too maybe a 28 inch barrel length ? maybe be able to get 3400-3500 fps. with the new Berger 135 gr. bullets ?
