I'm considering rechambering my Tikka 6.5 CM to the 6.5x284. I was looking on line today and it seems load data is a little sparse. I've got lots of H4831, RL16 and RL 23. I didn't find data for any of these. Is there a powder that is available now that would be better suited? I would be shooting the 140gr class bullets. Barrel is already cut and threaded @20".
