It's closest to 2400 in burn rate but it's a ball powder, vs. a flake powder.
I tried a pound several years ago experimenting with it when 2400 was scarce. Did fine in everything until I tried some in 45 Colt cases (+P loads) in a 454 Casull revolver & had two squibs, the only ones I ever had. Short story, use magnum primers or read the long story here.
