I have a new toy, a 6.5x300WBY. All the reloading data that I can find lists the older powders (h1000, 7828,5010 to name a few), not a bad thing. Does anyone have any data for some of the newer powders like Retumbo,RL 22 and 25 or others? I will be shooting Scirocco 130gr. or TXS 120gr. I would be interested in any 6.5 STW data as it is close to the same capacity.
