Videos tagged with Overpressure

This video demonstrates a critical ammunition failure scenario involving Turan Ammunition 5.56x45mm M193. The speaker, exhibiting high expertise, details issues like blown primers and failures to extract, leading to a jammed trigger group. The inspection of deformed brass confirms severe overpressure, prompting a strong warning against this specific ammunition.

This video explores the concept of "double charging" in firearms ammunition and its potential to cause an "exploded pistol". The presenter explains that while a double charge is dangerous and should be avoided, it typically only leads to catastrophic failure when the ammunition's pressure is already at its limit or when combined with other aggravating factors. The video suggests that a correctly loaded double charge, using a propellant with the right burn rate, can generate more energy without significantly altering pressure travel, allowing the firearm's mechanics to absorb the excess energy. A link to a previous video on "Setback" is provided, along with social media links and safety disclaimers.

This video from Kentucky Ballistics explores the terminal ballistics of bullets fired backwards. Expert instructor Scott demonstrates that while backwards projectiles can cause more immediate damage and energy dump, they also create unpredictable pressure spikes, potentially leading to firearm failure, as seen with the .50 BMG test. The experiment highlights significant differences in wound cavity creation and projectile deformation across various calibers when fired in reverse.
