Load help Dasher with 75gr

[Shawnba67]

I'm trying to find a working load for a 12 twist dasher. And 60 to 75gr bullets. I have a lb of 3031 anything else I would have to buy. Just for varminting.
Any recommendations for a 3031 load range? Its next door to N133/N130on the charts but I have no data for them either.
Anyone find success with cfe223?
Thank you very much.
