maybe have some time on the next weekend to make pics. a CNC lathe is great, you can make all kinds of cartridge systems. for pinfire cartridges you find so different ways to prime the fired case again. A little door on the side, base and tube fiting together with a thread and more.thats because we collectors classify the pinfire cartridge under "patent ignition systems".
i dont load a wad under my plinking roundball load but this is in a short case( hold only 65grain FG). When you need a real good cartridge for a shotgun barrel with 65mm long chamber load allways a wad under the ball. the short rifle case is not intendet for a wad, you need all space in the case for powder.
