The 6XC with light bullets
You could start with data for a 6mmX250 and work up as the XC is a bit larger. I'll have one going soon, throated for 70s and 80s. I'm thinking H4895 may be a good choice of powder for the 70s. Or something a bit slower may be better. We'll have to see. I'm thinking a big dose of 4350 may be great with the 80s.
