Question by Ben: any replacements for black powder?
me and my cousin are designing an American version of the Karyusha (yes, like the one from Sons of Guns) which is a Russian World War II Anti-Aircraft that can shoot multiple rockets out of pipes at once. my cousin wants the rockets to blow up in the sky, which I am against because then it would be considered as fireworks and we dont have a permit and fines are hefty for that. oh yeah, forgot to mention that it’s purpose is for airsoft and paintball war simulations, and this if it were for sale would be one-and-only and worth easily 5000$ in the ever-expanding airsoft market. it might cost 500$ to make. im not selling it though because of how it can be used for other purposes then I intend if it is even slightly modified. please dont give me a lecture of how this is stupid. i just want to know if theres a (legal) replacement for black powder that can be lit at ignition and propel the projectiles out of the 4 foot long PCB pipes. we were going to use 1 ounce of black powder at the bottom of the pipe if there is no substitution. if we were to explode the projectiles, which hopefully we’ll find another way that bbs can fall out of the sky and rain down on opponents (such as model rockets blow the caps off so if bbs were installed in the cap they would fly out, however model rockets arent reusable and expensive and use different launch system) if we were to explode the projectiles, I would use merely 1/8 of an ounce of bp. oh yeah and any ideas on what the projectiles should be? bottle rockets? foam rockets with bbs inside? plastic model rocket cases? firework cases (no explosives)? any ideas? just dont be obvious and say model rockets because of engine costs.
Co2 has gone into consideration, but my ignition system uses electricity to cause a spark remotely from a safe distance. Co2 is an area im more unfamiliar with although it would be less costly it would take away from the realism, and basically how badass it’ll be. if we do figure out a way to manipulate CO2 power or N2 with a paintball triggering system so that all can be released in one pull of the trigger we will definitely use that but were still figuring out our options and air pressure is the last in our list to check into. thanks for your help though!
Model, Im just checking my options here. could you offer me a suggestion or two? i have looked into spud guns and air cannons but they are too costly to have 8 of them but I’d be willing to pay if not for the fact that you have to spend an hour reloading them and cant do it mobile as you need an air pump. I want to be able to prepare everything but be able to reload it all in 20 minutes on the field. PVC can withstand 1 ounce of black powder. I’m not worried about that. the BBs are plastic and the worst they will do is make people bleed a little, paintballs will be more lethal though so thats out of consideration. I really need to figure out what the projectiles should be so can you help me there and I still need a different ignition source then black powder. Please? but thanks for taking the time to write me back.

Have you considered pressurizing the tubes with C02?
