Paladin,
As regards "flames" from the muzzle and smoke I can vouch for Pyrodex, 777, Swiss, Goex, Dupont, etc. That picture could have been with any of them. No personal experience with Pinnacle or its modern twin, other than that they do make lots of smoke.
It is only the "sparks", those bits of very poorly burning powder that vary among the various types of charcoal-based BPs, that is 777, Pyrodex, Swiss, Schutzen, Dupont, Goex, Elefant, KIK, etc.
Many years ago I shot a stage in early, deeply overcast morning in forest of big old trees. Last target was a flying clay that one had to bust before it hit a bunch of trees about 30 yards away. I smashed the bird quickly and there was total silence from the posse. Why? Well, the "flame" from my 12 gauge went all the way to the bird, which went "poof". It was jokingly said by the posse that my BP load had "cooked" the bird. The load was a volume of Pyrodex-P equal to 1,0 oz of shot, card and fiber wads, 1,0 oz of shot. Gun was a Husqvarna underlever hammer double with 75 cm barrels choked full and 1/2 -- the 1/2 choked barrel is what I used.
I have also ignited paper, cardboard, cloth, etc. targets with Pyrodex, Goex, Dupont -- never shot any close enough with Swiss or 777 to know. However, I suspect strongly that it is the burning embers that start the fires.
