1) A static electric spark can ignite black powder.
Umm... minor detail here... the chamber of most firarms (including all firearms under current discussion) is made of a special material chosen to have unfilled spaces in the valence energy band, allowing electrons to migrate between unfilled states. This actively disipates any intergranule static charges before ignition is possible.
In other words, the chamber is metal and conducts electricity well enough to prevent sparking. Same as powder flasks, which are either metal or electrically conductive (carbon impregnated) plastic for the same reason.
I have a wad behind the ball, and the balls are snug enough to shear a ring of lead. I don't see any need to put goop on top of those two seals for a third.
Oh, well if you are rich enough to afford wads for every ball... Seriously, if you don't have a wad behind the ball you should put some crisco in front. They both do the job. I prefer the crisco because a) it's cheaper, and b) it seems to soften some of the fouling... but no worries either way.
