Your Clean Shot loaded bore needs to remain outdoors with moisture surroundings in order to witness it's lessening/hangfire effects along with dripping/droplets of powder when the muzzle is pointed downwards after hunting in wet conditions.
My tests were conducted/proven with it's sister (American Pioneer) last fall. I left the two front doors of my pickup open with the tightly-capped powder on the rain-protected front seat for a few hours along with subjecting it to a couple of mild (25 degree) temperature changes moving it from auto to trailer... back to auto. That's all it took to create a non-working environment.
I used it in the Adirondacks a year ago, where it rained every day for a week while I was there. I put a band of plastic wrap over the muzzle, and a wrap around the (side) lock section also. Unfortunately, I got no shot at game that week. But when leaving, I fired the load that had been in the barrel all week (gun left in the truck at night with the cap removed from the nipple). It fired perfectly. IMO, if proper precautions are taken, the same as would be necessary to keep black powder dry, it will serve as well as BP or Pyrodex. Maybe not as well as T7. I haven't hunted with T7.
