Is there a newer and better powder for loading 357 mag than the 2400 powder ?
Let me know if you find something. I'm been using 2400 in 357 & 44 Magnums for about 40 years and I haven't found anything that works better in my magnum revolvers.
Why do people think that if a powder has been around a long time its no good any more? Look at Unique and Bullseye they still work pretty dern good.
New isn't always better.
