Bullet Stability & Twist Rates | Applied Ballistics with Bryan Litz
This video, featuring ballistician Bryan Litz, delves into the critical relationship between rifle barrel twist rates and bullet stability, particularly for long-range shooting. Litz explains that faster twist rates are necessary to stabilize longer, heavier bullets with high Ballistic Coefficients (BC). He highlights the importance of achieving a Gyroscopic Stability (SG) factor of 1.5 or higher for optimal flight and recommends using tools like the Berger Twist Rate Stability Calculator, while also pointing to his extensive books for deeper understanding.
