30-378 load data

Re: 30-378 load data

H-1000 is in the Hornady book but not for the larger grain bullets. Retumbo is not in the book I need more info. I think 50 BMG would be good?
Has anyone tried RL25 ?
What bullet, powder, primer are you using? SD, ES, expected barrel life?
I know this round is a barrel burner but he wants my input, this is why I'm asking.
Any other help is appreciated
Thanks NF
