Lost Arts Part 6: The Ultimate .410 Shotgun
This video tests the structural integrity of a .410 single-shot shotgun when fired with high-pressure handgun and rifle cartridges like .454 Casull. Despite significant pressure, the firearm showed no signs of damage or barrel stretching, though projectiles keyholed due to the smoothbore. Terminal ballistics tests demonstrated impressive expansion of the .454 Casull round.
