Clean burning PCC powder

[niftyfifty]

I've been loading handgun ammo for over 30 years. I used W231 forever. Just started loading for my 9mm SBR. (which has a HUGE appetite). Started out with 231 loads. Then switched to CFE Pistol. After about 3k rds I've decided to look for a cleaner burning powder. 231 and CFE are extremely dirty. Looking for any recommendations or personal experiences. BTW no signs of copper fouling wth CFE. Just alot of soot.
Thanks

VV N320 or N340 are really clean.
