A few months ago Jeff from TAOFLEDERMAUS received some tripwire alarms designed for blank shotgun shells.
He took this opportunity to show what happens if a real shell is fired outside of a weapon.
That first video was made to explain why these alarms would make terrible traps. Most viewers were confused, and suggested that Jeff wrap the shell with duct tape or use a brass cartridge instead.
Jeff listened and decided to find out what happens when the same alarms were loaded with .50 cal BMG cartridges.
See the results in the video below.
