This is a slightly improved version of the potato gun ammunition, the math says it should travel about 325-350 feet with 100% or 75% infill, that is if you are using compressed air at 80 PSI, for propane guns it is about 190-225 feet (Due to the propane only hitting 46 PSI). And so far the math seems to be correct. You do need to use wadding to get a good seal though, I use toilet paper, but anything that can keep it in place with no gaps will work. They do tend to survive a few shots if they don't hit something like a Metal plate or concrete at point blank range, I had one of the 1.0 bullets last 15 shots before I lost it.
You can print with supports for better quality or without supports.
I do recommend a bed for easy removal and better quality, but you don't need it either.
100% infill works, but I use 75%.
