I have a few powders I really like, but 2400 is one of a couple powders that I absolutely LOVE.
I feel like I'm saddled with 3/4 of a pound of Unique. Probably end up sparking a camp fire with it when I'm sick of looking at that crap.
But 2400? It's my go-to powder in .30 Carbine Blackhawk loads, it's my main squeeze in jacketed .44 Mag loads, it's my favorite in 125gr and 158gr .357 Magnum boomers and I also use it to great effect in .327 Federal Magnum. Currently, I'm also using a crapload of it to make terrific 240 grain loads in a .460 S&W Magnum, and I'll
hope I'm around 1,900 FPS with it. (a chrono is in my future)
I haven't yet tried it in 10mm, but I plan on it.
2400 is not a powder you need to "get rid of", 2400 is a GREAT powder!
