Note that the blue one was for breech loaders so could be loaded into a cartridge. The copper wire basket construction was filled with shot of a size that would come steadily through the holes as it flew down range. This was mixed with bone meal. The whole was then wrapped in paper which came away as the shot emerged. The one on the right shows the outer paper wrapper with pull cord. This could be removed and used as part of the wadding. The main wad was part of the paper wrap and wire cage for easy loading. All very neat. Lagopus.....
