340 Weatherby 265 TTSX anyone have any experiance loading for this

Just an update I phoned Barnes the best result was with Ramshot Hunter min 68.5 - max 73.5
other powders they used were ------------------------ H 4831 74.0 - 79.0
------------------------------------------------------IMR 4831 73.0 - 78.0
------------------------------------------------------Reloader 22 77.0 - 82.0
I read an post on Longrange hunter magazine as well where IMR 7828 is being used with good results
 
Just imagening the length of that bullet relative to the standard bullets normally shot in.338s
And I did not realize the 340 comes with a 1-10" twist.

Elmer Kieth at work again.
