I've given up on finding 2400, one of my fav cast powders. But I bought an old metal can of Winchester 540 from an estate sale. I've read it's basically Hodgdon HS-6.
its burn rate is in the neighborhood of 2400.
Does anyone one have any load data for 30-30/165grain boolits or thereabouts? I can't find anything.
Otherwise, I'm going to start with 13 grains and work up an accuracy load-not looking for speed.
