I'm looking into getting some Nylon casings made at a local plastic injection shop. They'll be empty but will be easy to load. Design will use the retired black film canister (you know, before stuff went digital) as a payload. Most shoppers drugmarts photo labs (or any other photo lab) will give you a garbage bag full for free. They just recycle them. Shotgun primer. You can fill the canister with whatever you want. You can put an army man with a parachute inside the canister (no lid) and launch that. Should fall out and float to earth.
I'll experiment lots more once I have the casings.
Anyone else interested?
I don't have any quote yet, shop said they can do it, but they want drawings. Working on those now.
I don't plan to sell any loaded ones. I barely have enough time to shoot.
