This video demonstrates the dangerous consequences of firing incorrect ammunition calibers in firearms. Experienced instructor Matt Carriker shows how .380 ACP in a 9mm firearm and 9mm in a .40 S&W firearm can lead to cycling failures and severe brass deformation due to improper headspacing. The experiment highlights the critical importance of using the correct ammunition for each firearm to ensure safe operation and prevent damage.

This video from DemolitionRanch, featuring firearms expert Matt Carriker, tests the ballistic resistance of Flex Tape when used as improvised body armor. The experiment involves layering Flex Tape onto cardboard and testing its effectiveness against .22 LR, 5.7x28mm (FN PS90), and 9mm (CZ Scorpion Evo 3 S1) rounds. The results demonstrate that even extensive layering of Flex Tape is insufficient to stop common firearm calibers, highlighting the importance of proper ballistic materials.
