Your favorite powder for 9mm

I use Tightgroup for minor factor IPSC loads,most consistent powder that I have ever used for this calibre and cheaper than most.

For heavier loads I use HS6,which shoots soft,but is a bit dirty.
 
I have two I like: Winchester Action Pistol and Winchester 540. Guess what? Both are discontinued. HS-6 is the same as 540 though.

These powders require somewhat larger charges than 231, but I have found the somewhat slower powders to be more accurate with cast lead 124 to 135 grain bullets.
 
I have a perfect powder for the 115 gr fmj load. It meters perfectly well in the Dillon, fills up the case nicely, is accurate in a variety of pistols (just over 2" at 25m), cronos about 1160 fps consistently and has mininal flash at night but I am keeping it a secret.
