This topic is kind of an offshoot of a previous thread where safe loading of flintlocks and percussion guns was the topic.
Unlike percussion and flintlock rifles,... where a lubed patched roundball seated upon a charge of black powder is normal procedure, smoothbores can be a different animal altogether.
Sure,.... a lubed patched round ball can be loaded in a smoothbore (pretty much the same as in a rifle), but what about all the other ways a smoothbore can be loaded?
(We can get into "Buck'N Ball", and "shot loads", in another thread.)
Just off the top of my head, I can think of a few different ways a smoothbore can/might be loaded,....
1. Powder,... lubed wad,.... ball,.... card wad.
2. Powder,.... wad,............ ball,.... card wad.
3. Powder,.... wad,............ ball,.... tow or blanket wadding.
4. Powder,.... tow,............. ball,.... card wad.
5. Powder,........................ ball,.... tow or blanket, grass, leather, and even tree leaves
for wadding.
6. Powder,........................ ball,..... and nothing except the fouling (from
previous shots) to keep the ball in place on the powder charge.
From the research I've done (mostly by reading old journals) it seems as though #5,... and #6, were pretty much typical "back in the day".
Of course "ball size" plays a big role in how accurate the above loads shoot, and balls can range anywhere from a measly few "thousands" smaller than bore size,.... to 0.020" smaller than bore size, and achieve a passable form of accuracy out to 50+ yards that can rival a rifled bore.
I'd like to hear some thoughts on this, as well as YOUR favorite technique when loading your smoothbore.
Due to cold weather and old bones, I haven't got much load testing done this winter.
