I recently picked up a current issue inert U.S. M67 grenade with the markings on the top surface. The code for the loading plant on it is STL which was a code I didn't recognize and had a hard time tracking down. Any Google search for STL returns millions of hits about St. Louis, Missouri and nothing about hand grenades. A friend let me know it stood for Spectra Technologies LLC, a new ordnance loading and production facility in Arkansas.
Their video seemed quite revealing regarding processes and techniques and includes some great test explosions near the end.
