Re: 257 wby loads
Ah, the .257 Weatherby Mag. I love that caliber.
I run a pretty hot load in mine so be careful and work up to it. I get 3725 fps out of 72.0 grs of RL22 using Barnes 100gr TSXs. Keep in mind that RL22 is temperature sensitive and running a hot load with this powder in hot weather might cause problems.
