I've been looking into rebarelling my 257 Wby that currently has a 10 twist Krieger barrel on it. It's only a matter of time until it's toast because I've been pushing it hard with 115 Bergers and RL25 powder at 3600+ FPS.
Currently it looks like Blackjack is the longest running maker of high BC 25 cal bullets but they only offer the ACE and it appears to be a target bullet. I know that Hammer makes a 128 grain bullet but the advertised BC is wayyyy lower than the Blackjack or the newer Berger bullets that are on the horizon. Are there any other options out there?
As to barrels my Krieger has been fantastic but I'm not married to it. I also have a Brux on a 260 AI that is a shooter. I've read that a 7 twist is too fast for the 257 Wby So what twist is recommended?
