340 Weatherby/H1000/250 accubond

[mtnwrunner]

Howdy all. Anyone have or can suggest a starting and maximum load for a 340 weatherby using H1000 and a 250 accubond? I've done quite a bit of research and can't find squat. I shot yesterday using RL22 and it did pretty good but the velocity was a little low. I'd like to try H1000 as it has always worked for me in other calibers.

Thanks, Randy
