That same thought entered my mind as i bought it...."play with it?! Heck, I'm gonna TOTE this sucker."

Muzzle is sealed by greased patch, waterproof caps snug and firmly seated with constant hammer pressure....gun and touch hole and nipple were clean and dry before charging, 3f black powder used for surest ignition, and if you are ever worried about THAT part, can always remove nipple after charging, trickle a little 4f in the touch hole, and even put a few grains in the nipple before capping.....it WILL fire.
