257 weatherby help

[SouthLoganCountyShooter]

Anyone loading absolute hammer 90g in 257wby? What powder are you using. I have imr4955 Imr4451 re26. Can get imr4831. What seating depth?

I've loaded up to 67g imr4955. Has pressure sign and slower speed
Loaded up to 76g re26. Speed came up but gun doesn't like 26. Help new weatherby vanguard high country custom.

Email or call Hammer. That 90gr absolute is advertised at 3900 FPS. Would like to see the reply.

I worked up to almost 78 with RL26. I don't know if you were getting pressure signs though. Also your barrel could need some rounds through it before you start to find something it likes.

Are you running hammer bullets?

Look at Hammer Hunter Load Data thread. Most everyone is getting high 3800 to over 4000 fps. Several powders.
