What is your favorite milsurp cast bullet powder?

I am just wondering how many of you out there are reloading cast bullets in your milsurp rifles.
I have been doing so for about 9 years now and have found Alliant 2400 to be the most versatile and accurate powder for this purpose.
I'm currently loading for .223rem/5.56mm, 7.62x54R, 8x57 Mauser, 8x56R, .43 Mauser.
Chime in and let me know your thoughts and experiences.

I buy my 2400 in Alliant cans, so it isn't milsurp.
I like Red Dot (can't remember now what was the "universal" load?), Unique, and 2400. For closer to full-house loads, the IMR powders always did real well with lead bullets.
I haven't done any lead rifle shooting in a LONG time, so don't remember my "favorite" loads.

I'm referring to the firearms being milsurp, not the powder.
