Great, now you have to worry about being killed with silly putty!YouTube
We shoot Silly Putty from a Mossberg 590, 12 ga. shotgun at various objects. It surprised us that it even made it out of the barrel in one piece and hit what we were aiming at.
The shooter is Matt and has a Youtube channel mostly related to RC stuff. http://www.youtube.com/user/Jackismycopilot
