Now I am used to variances in load data from different sources but this seems to be extreme??
I normally use 2400 but wanted to try a milder load. They are almost the same data for the 250 grain Keith with 2400.??
So, I be a bit confused here.

Sir, if you'd like to really confuse yourself, go back to Alliant's online guide and look at the page for .44 magnum with a cast 250-grain Keith bullet. The max listed for Unique there is 11.0 grains.
FWIW, my own experiments with .44 magnum, cast 250s, and Unique turned up accuracy "sweet spots" at 8.5 grains and 10.0 grains.
Hope this helps, and Semper Fi.
