45 Y/O S&W Police Slugs - Anti-materiel Sabot Rounds - Tested

We have a rare opportunity to test out some unique 12ga. slugs that S&W tried to convince LE agencies would be a good idea to adopt. They claimed they would penetrate automotive engine blocks, which would disable the vehicle. In order to do this, the slug would have to first pass through other obstacles along the way and with luck, it might hit something vital on the engine. Whether or not these slugs were EVER successfully deployed in this manner, we may never know.
