2400

[Rocky Raab]

You didn't do anything wrong. Alliant 2400 almost always leaves a few (or a lot) of unburnt flakes behind. Unless they gum up the action of your revolver, just ignore them. Really.

Two things can help, though. You can increase the charge, which adds to the pressure and thus also to more burning. Or you can switch to a more suitable powder for mild loads, as skeet suggested.

Unique is an old standby, and 8.0 to 9.0 will be not only cleaner burning but possibly more accurate than a reduced charge of 2400.

If you ever need to load that .44 to its max, then come back to 2400 for maxi-oomph. Even at high levels, you'll still see some unburnt flakes, though.

Oh, some guys recommend magnum primers with 2400, but all the old-timers as well as Alliant recommend just standard strength primers for 2400. I've tried both, and standard ones work better for me.
