Theres a video on youtube but it really doesn't do a good job of showing the damage on target. Anything shot out of a gun has the ability to be deadly, even airsoft pellets, I would stick with market rounds like bean bags if anything. I don't suggest trying to mods shells unless you know what your doing but usually that doesn't stop people anyway so if you try it make a video of it so we all can learn.
But like I said I do not suggest doing this...
