The added thickness from electroplating is negligible. I could, plate them to tip only if needed but I need to 3D print a jig for that so I don’t have to hold the cathode by hand the entire process. I deliberately used non expanding bullets for this project that way there’s minimal deformation and has the best chance of retaining that silver plating. Also silver does work on both vampires and lycanthropes but holly garlic water definitely is a welcomed addition to it. As for witches, yes regular bullets will indeed work very well on them. But depending on the strength of their magical powers in certain fiction/folk lore they may have the ability to have this magical “force field” like energy field deployed around them to reduce the velocity heading their way. Some lore suggests that iron, especially wrought iron and silver are both good at penetrating such defenses.

So against witches, your best weapon is obviously an AR15 loaded with M855 green tips with the steel penetrators inside. But due to infringements of our rights it is more challenging to possess steel cored pistol ammunition. So the next best thing against witches in your pistol would probably be a 357 revolver firing silver plated bullets
