If you do not know what a SQUIB LOAD is and how to recognize it, it is strongly suggested you learn ASAP.
Technically defined, a squib load is an underpowered charge. That underpowered charge could result in a barrel obstruction.
A squib load is most notably recognized by an odd sound. While shooting, should you hear an odd sound, a sound different from the big bang, kaboom or crack, you normally hear or only heard when firing that last volley of shoots, CEASE FIRE immediately, following safe gun handling practices, inspect the gun for a barrel obstruction.
Firing another round, following a squib load, that resulted in a barrel obstruction, could result in the firearm blowing up in your hand and you loosing parts of your hand as a result.

The recalls above are the most recent (June 21, 2021) of two known ones. At the pace manufactures are turning out ammunition, in an attempt to catch up with backorders, quality control has diminished. Always be alert for the occurrence of a squib load and the possibility of a barrel obstruction. It can happen with any ammunition domestic or imported. Be vigilant, be alert, be safe.
