Yes, the Bow Mag, an exploding arrowhead using a real revolver cartridge.It's the Rac-Em-Bac Bow-Mag bullet tip. It's an arrow tip for archery where a .38 special/.357 round is inserted and the firing pin is screwed into the arrow shaft and tip. Upon the arrow striking the target, the firing pin hits the primer to give the arrow more knockdown. Pretty cool.View attachment 3713807
Apparently they are not easily detonated when striking meat or tissue, but hitting sheet metal or plywood sets them off reliably.
