Thanks for the info. I have a .357 Smith so I might just keep it to load for that gun.I think not...
It's a relatively fast burning powder primarily designed for magnum revolver cartridges. I've used it in 44 Mag, 454 Casull, 45 Long Colt, and 357 Mag cartridges.
I do not think it will be useful for loading 270 Win.
Google search "Alliant 2400 load data"...
IIRC Unique and bullseye go back that far alsoI think this 1lb can dates back to the 1950s or 1960s.
I read that 2400 was first manufactured in 1932.View attachment 394175
