N ever heard of it.  Knowledgeable flinters can shoot in the rain   

It is an extremely fine white powder.  Not flammable. The instructions say to mix well to coat the powder well.  I only found 1 vague reference to it when I searched.  It is so rare that it is likely  worth twice as much as I paid for it. How much is twice nothing?

Wonder if a flinter will set it off if it coats the powder? 

I remember getting a hold of some some powder that did not ignite very well.  I think it may have been Elephant when it first came out.  I ordered powder from my regular source and they shipped Elephant.  First I ever heard of it when it showed up at the door. I remember selling it and everyone else shot cap locks.

I always used 4f for target shooting and dry day hunting.  I used 2F same as my charge on wet days.

Same here, know of it, but never used it or have NEEDED it frankly, as have none of my flinter BP friends.

As stated, if really wet or humid out, 3Fg in the pan is less hydroscopic and polishing the pan helps some too. Three of us spent 6-days in a primitive MZL’ing camp in VT’s late MZL season and it rained for 4-days, where we had a good foot+ of snow when we started and had brought everything in on a toboggan.

I had to leave on the 5th day (duecto an emergency) when the rain had stopped and it was 20-degrees & frigid out due to the wind. I could not for the life of me pull the load that had been in the barrel all week long, so being as I was in a hurry, I just shot it out. The ignition was instantaneous ... and was only 1” low offhand at the spot I aimed at 50-yds away.

For most of the hunt, I didn’t even use a ‘cow’s knee’, I just kept the muzzle down and the lock area tucked up under my armpit.
