Clean powders for suppressor use

[Old Man with Gun]

I am shooting almost everything suppressed these days and am finding a lot of my pet loads are dirty as hell.

I want to open this up to any caliber subsonic or supersonic with the focus on clean burning powders.

Feel free to post full load data or just your experience with how clean or dirty different powders are in various calibers.

Xbr in a 223 bolt gun has been cleaner burning than any of the other temp stable powders Iv tried in about anything.

Hundreds of rounds of Xbr 223 don’t do what a couple dozen of whatever with h4350 does in my suppressors.

I’ve been using CFE blk with great success in 300blk super and sub also super 556 using AAC 7.62.

All Hodgdon extremes are pretty clean minus Retumbo. Almost all Alliant or Viht 5 series are pretty dirty. 8208XBR is clean. Imr enduron are middle of road clean/dirty. This is my experience with Centerfire supersonic loads.
