There is speculation an ordinary carpet tack in a standard shotgun slug will turn it into an armor piercing projectile.
This video puts that theory to the test with one very thorough experiment.
Watch and see if an ordinary carpet tack can turn a standard shotgun slug into an armor defeating slug.
There have been many urban myths about an ordinary carpet tack turning a standard lead shotgun slug into an armor piecing slug, and Taofledermaus couldn’t help but test it out.
So how well does it actually work? Against AR500 armor plate, it was not a success. For other materials, it may give a little more penetration, but for hardened steel it certainly is not armor piercing.
Leave the tacks and shotgun slugs at home and pack a rifle if you want to punch holes in steel.
