I have used the Berger 135gr and H1000. I think I started at 63gr. I am still doing development with them in my 257 weatherby but they are good so far in my 1:7 barrel.

I'm shooting the 134gr ELD-M in a custom Tikka. 24" bbl , chambered in 25-284. fluted Brux 3 contour in a 1-7 twist. Custom Manson reamer . I had set up for the 134gr to have the boat tail shank junction just slightly above the neck shoulder junction. It's accurate and fast.
The load I settled on was 3163 fps with RL-26. SD-2.2/ES-4. Shoots under a inch at 300 yards.
