This video explains the concept of a double load in ammunition, where excessive powder is used. While modern firearms are built with significant safety margins, a double load can become dangerous when combined with other factors like fast-burning powders, oversized bullets, and aggressive primers. The presenter, an experienced gunsmith, details how these factors can lead to overpressure, case failure, and potentially catastrophic firearm damage.

This video details the aftermath of an ammunition 'kaboom' event, focusing on the damage to a firearm's bolt face and ramp. It explains how overpressure or setback can cause the cartridge case to expand, copying the firearm's components. The instructor highlights the importance of the extractor channel's role in venting excess pressure and discusses the differences between a true kaboom and a setback event.

This video explains how a bullet setback, caused by improper case resizing and excessive powder compression, can lead to dangerous pressure spikes in handguns. Reloaders are advised to carefully select components, properly resize cases to maintain neck tension, and use propellants suited to the caliber to avoid a 'perfect storm' of conditions that could cause firearm damage or injury.
