This "Daily Defense" episode delves into rifle ballistics, focusing on external ballistics and their impact on AR-15 platforms without complex math or graphs. It explains how gravity, air resistance (affected by temperature, altitude, and humidity), and height over bore influence bullet trajectory. Key concepts like initial intersection, maximum ordinate, and terminal intersection are detailed. The video also touches on terminal ballistics, highlighting how bullet velocity at impact and bullet fragmentation affect wounding capability and lethality in self-defense or hunting scenarios.
This video from Brownells Gun Techs, Caleb and Steve, dives into the concept of ballistic coefficient (BC). They explain that BC is a measure of a bullet's ability to overcome air resistance, with higher numbers indicating better performance. They illustrate how bullet shape, like long and narrow versus short and squat, impacts BC. The discussion highlights the importance of BC for long-range shooting and mentions its lesser significance for shots under 100 yards. Caleb also touches on scenarios where a high BC bullet might not be the optimal choice. The video encourages viewer interaction in the comments section.
