So caseless or binary propellant bullets are a good idea as a bullpup?Bullpups are more useful in certain specific situations. However, the tradeoffs they make to reduce overall length tend to be a net negative in generalist use.
I would specifically call out:
Solving the trigger issue, in the U.S. as least, is difficult due to the regulatory climate. The other two issues I'm not sure can be solved at the design and physical level, not within the design of semiautomatic gas or recoil driven firearms anyway.
- Longer trigger linkage complicating design, maintenance, and longevity. Technologically, soultions (say a reliable solenoid trigger or electrical primer) could mitigate this if they're bulletproof(heh) enough.
- Gas system operating closer to user's face increases long term health risks from propellant and byproduct
- In field use, dealing with varying shooting positions and malfunction clearing can be more problematic. I am not 100% sure on this one, is this as much of an issue on modern bullpup patterns?
All that said, if you want to shorten overall weapon length and dont care as much about the other concerns, the bullpup is a clever and useful engineering solution.
You had caseless rounds so there was no need for an ejection port, except for the one on the bottom in case you had a dud round.
In BP Bullets you inject two chemicals that when combined become explosive. A spark like in a car engine can ignite the mixture and send the bullet on it's way.
