This video from Brownells Gun Techs explains the concept of Ballistic Coefficient (BC), a crucial factor in understanding bullet performance, especially for long-range shooting. Caleb and Steve detail what BC represents – a bullet's ability to overcome drag and wind resistance – and how it's typically expressed as a decimal less than one. They highlight that a higher BC number indicates a more efficient bullet that flies flatter and is less affected by external forces. The explanation includes practical examples, contrasting the BC of a long, narrow target bullet with a short, squat .45 ACP round. The video emphasizes BC's importance for distance shooting while noting it's less critical for close-range engagements, with Caleb offering insights into why a high BC bullet isn't always the optimal choice.

This video, presented by an expert firearms instructor, investigates the effectiveness of soft body armor against rifle rounds under specific, best-case conditions. It details a test involving a windshield as a barrier and soft armor, demonstrating that while soft armor alone is unlikely to stop a rifle bullet, its survivability potential increases significantly when combined with a barrier like a vehicle windshield. Future testing with different calibers is planned.

This guide, presented by a Brownells expert, details how to accurately measure and read an analog dial caliper. It covers taking outside diameter (OD), inside diameter (ID), and depth measurements, with a practical example of measuring a 6.5mm bullet. The explanation emphasizes understanding the main scale and dial face for precise readings, crucial for gunsmithing and reloading applications.
