So rimless cartridges can't be 3d printed?
Will rimmed cartridges feed in something like an FGC-9?
>Another better (in my opinion) solution is to not even have a rim on your case, as mentioned. I don't have acess to the design files, but Im messing with a forward extractor design thats basically... Take your chamber, now cut a groove into it. At the front of this grove you have a spring loaded lever that sits and pulls the case from its head. Think an external extractor on a 1911 but its actually a part of your chamber. When your bolt comes back, it actuates on that extractor lever, pulling your case out. Theres better, closer approximations but I don't have my notes.
That would be quite hard to implement, drilling even a basic chamber is not an easy task

>An idea to make more effective weapons in a place where you can't get brass cases is to make a disposable barrel with stacked loads like a roman candle, basically 3d print a sleeve that fits into a section of seamless hydraulic tubing, with 5 or so shotgun loads stacked sequentially inside, with gaps in the plastic for metal contacts to be fitted, the barrel can then be locked into a grip with a battery and trigger, you fire off the shots sequentially, when empty just remove the barrel and slap in a fresh one.
If I understand you correctly.. How are you going to ignite the powder if they're stacked in sequence?
