Your right on the light source.
I tried out the tri ball and at 10 feet it did not penetrate a old carhart nor leather jacket, it did dent the hell out of the ply wood behind it, I havnt tried it on any more to save the last two but I wonder if it would punch through cotton. The bean bag just dented the wood a little with the carhart on the wood so I would think this will be the best round for non leathal Amunition given my houses lay out, I'd rather not kill an unarmed man.
