Designing a non-lethal OC selfdefense cartridge, please help.
(OP)
Hi guys,
I'm new here and wanted to ask for an advice.
I am looking forward to develop a 15x90mm selfdefense cartridge, here's my drawing of how I see it.

This cartridge will contain.
1. a blank .22 round in the back
2. cartridge body ( shown in grey )
3. a cap ( also shown in grey ), that covers the front end and has a nozzle
3. a plunger ( black )
4. OC - pepper spray - solution
5. and a plug ( black ) that plugs the nozzle in the cap
When the .22 round goes off, its supposed to push the plunger and propel the OC solution out of the nozzle.
What do you think about my design in general? What materials do you think should be used for body and cap, considering that the .22 round gives off 45 joules of energy. Polycarbonate?
Thanks! :)

* Can not see how you're going to mould the serrations inside the end, nor how you are going to achieve a leak-proof seal.

It's ok to soar like an eagle, but weasels don't get sucked into jet engines.

Nope. Not with those sharp corners at 90º to the line of draw. Nor in LCP. A thread would be ok but adds tool cost.

Buy one, burn it and smell it.

That is a legal question and may vary largely from country to country or even state to state or province or whatever.
I have over 40 years experience in the plastics industry and I am considered by my peers as expert in identification. I would not presume to guess any plastic purely on looks, even for real and up close. From a photo, surely your kidding.
SG and burn tests are good starting points. Melting point can be a good second level for confirmation or final sorting.
The translucent white classifies it as almost certainly semi crystalline. That's a pretty big group.
