Videos tagged with Band Pressure

This video delves into the complex physical factors that contribute to firearm barrel wear and potential failure. It explains how projectile engraving, band pressure on rifling lands, energetic propellant forces, recoil, vibrations, and thermal stresses all impact barrel integrity over time. The discussion highlights the unpredictable nature of some of these forces and their long-term effects, particularly focusing on thermal stresses and their metallurgical and mechanical explanations.
