Felt wads and yellow jackets!
I'm with Doc Hoy on the felt wad issue. I have shot percussion revolvers for 16 years and always thought that felt wads were for people who wanted to spend money...
I usually used cream of wheat or nothing, and smothered crisco over the ball to help with fouling. After seeing the post on home-made wads, I just bought the felt and beeswax to make them on the cheap.
I do believe that this is the first time I've heard of shooting wasps with a pistol! Well done. I did once shoot a wasp's nest with a full chamber of powder and no ball. Big black spot on the roof of the shade canopy, and no nest remaining...
As mentioned in a previous post, there is a wealth of info on cap n ball revolver shooting/tuning here and on other forums.
