.338-378 Weatherby mag

[Ridgereaper]

I know its a long shot, but does anyone have any load data for the 270 gr eld-x? Looking for starting and max loads for H1000 and Retumbo, possibly Rl-25. So far I’ve averaged what I can find for 265 and 275 gr bullets and loaded some rounds up. Just wondering if anyone has something better to start with, or some better advice.

So far I’ve loaded 10rds of each with new Norma brass and CCI mag primers

H1000
100 gr
102 gr
104 gr

Retumbo
102 gr
104 gr
106 gr
