FYI, Powder Valley now has a few powders available.

One is Alliant 1200R, which is reportedly designed for the.223, so it would probably work in the .358 Win, etc.. It's not that well known, so people don't seem to be grabbing it up.

PV also has X-Terminator and Vv24N41, a slow burner good in big cases, like the 26 Nosler, etc.

Midway has Ramshot LRT. I never heard of this one, must be new. It's said to have a burn rate similar to Retumbo.

Again, somewhat unfamiliar powders not being grabbed up as fast as better known powders, but probably good performers.

If you see a powder you can use, better jump on it. May not be there next time you look.
