Anyone know of any data for Hybrid 100V in the .378 Weatherby - particularly with the 300-gr Swift? I like what I have seen of the powder so far (in the .416 Rigby) but I can't locate any data for it for the .378.

Hodgdon does not show anything on their website, and I do have a request in with them, but I was hoping someone here might have spotted some data elsewhere. Thanks.

Way too fast for that caliber. I tried it in the 8mm Rem Mag with poor results.
