Videos tagged with Cartridge Pressure

This video addresses the common practice of cycling carry ammunition and its potential implications. The presenter explains that repeatedly chambering and ejecting rounds can lead to 'setback,' where the bullet is pushed deeper into the casing, potentially increasing internal pressure. While modern firearms and ammunition are robust, this phenomenon is a factor to consider for reliability and safety. The advice is to inspect carry ammo for signs of damage or setback and to replace any suspect rounds to ensure optimal performance.

This video from Brownells experts Caleb and Steve addresses the common reloading myth of interchanging rifle and pistol primers. They explain the critical differences in primer cup thickness and height, detailing why using pistol primers in high-pressure rifle cartridges like the .223 is dangerous due to insufficient pressure containment. Conversely, they discuss how small rifle primers can sometimes be used in high-pressure pistol loads if the firearm's mainspring is robust enough, and why certain high-pressure cartridges like the .454 Casull are designed for rifle primers. The experts strongly advise consulting reloading manuals for safe and reliable practices, emphasizing that while some interchangeability might be technically possible with extensive load development, it's generally a risky endeavor.
