With a background in electronics, just looking at that gun, it seems very unlikely it would do more than give someone a bruise. That appears to be a single coil which is chonky as hell, which means you need a high voltage to drive it. It looks like it also only has a single capacitor, the physical size of the which is too small to have enough energy to seriously drive a coil like that. You can find videos on youtube of diy coil guns 5x the size that at best punch holes in 3mm particle board or one side of an aluminum can. There is no way that thing is actually going to kill someone.
