257 WBY load found I think.

Took my 257 Wby out today loaded with N570 at 77.0 grains. The load was way faster then I had hoped and shot just under .750. It chrono'd at 3574 fps with an ES of 2 and SD of 1. All of this tested with a friends Lab Radar I was blown away with the results. My old load was 100gr TSX at 3602. So this load is knocking right on the door of that. Just need to sight in and wait to teach a deer a lesson now.

What bullet, primer and how far off the lands. I have been looking at some of the faster .25s.

Thanks
Dave

Guy I shoot with loads the 100 gr ttsx
In his with RL 26 and he is right at 3800 FPS. Kills big game very fast .

Left Hand Dave I forgot that part of the equation sorry. Using the 110 ELDX seated to 3.500. The length needed to touch rifling would have been 3.642 and bullet would not have seated then. My primer chioce is the Federal 215. My rifle is a Remington 700 factory rifle with 26 ibch barrel.
TrmB2 I would really like tofind some RL 26 to try in a few of my rifles.
