Stage 1. Hammer at full cock. Frizzen covering frizzen pan.
Stage 2. Hammer falls forward, simultaneously knocking the frizzen back, exposing the 4F powder in the frizzen pan and creating sparks by scraping the flint down the face of the frizzen.
Stage 3. Powder in the frizzen ignites and hopefully sends fire into the vent hole in the side of the barrel.
Stage 4. Powder in barrel ignites, sending a jet of flame back out through the vent hole and sending a foot long flame out the muzzle of the barrel.
