my quest for flashy 9mm sutable powders continues... 
I know slow burning powders are supposed to have larger muzzle flash, but I used enough powders to know that’s not always the case. For example Power Pistol is faster burning than Herco, and Blue Dot but has more flash (in my experiance).
I've head sure some powders contain flash suppressants. Anyone knows what powders have them? Or what powders simply give more muzzle flash?
BTW anyone tried VihtaVuory’s N350 or 3N37 powders how are they?
Don’t ask me why I want flash I just do
