2400 vs. IMR 4227

I'm about out of IMR 4227, a powder I've used for about 8 years and really like in my .44 Mag.  I found a load that works and shoots great in my Ruger Vaquero.  I'm switching over to some cast bullets 300 grain, WFN and figure I might go to 2400 to see how well I like it.  I'll also load my .357 Mag and possibly some heavy .44 Special loads.  IMR 4227 has been a little dirty for me in the past, but shot well.  Is 2400 any cleaner?  If so, how is accuracy.  Essentially, which do folks prefer and why?

there both realitively dirty powders but who cares. If a guy is to lazy to clean a gun once in a while he needs a new hobby. I like both of them 4227 is a litte better on the top end of the load scale and 2400 is a little better if you want to load down a touch. But both will do about anything in a mag pistol case. Ive probably had a little better luck with accuracy using 4227 but to get it you have to keep pressure at least in the midrange level to ensure burning and use a mag primer.

Many powders leave a bit of "soot" in the bore.  The next shot removes it but leaves its own but that's not a problem since it doesn't accumulate beyond what one round leaves.  As you observed, it doesn't harm accuracy and if performance is good who cares?  It is easy to clean with a patch and bit of solvent anyway.
