If I understand correctly, I can legally shoot CN, CS, and Pepper from a Non-DD launcher. I was thinking a ping pong ball could be filled with pepper by drilling a 1/2" or smaller hole. The hole could be sealed with tape, then launched.
I was thinking various types of pepper could be used. The cheapest and most easily available would be regular table pepper. There are other peppers of course, some much finer ground which would help with dispersion. Could the liquid hot sauces be used, or could something like vegtable oil be added to the dry pepper for better spread.
