General trends. Sporting bullets have BC's in the range 0.12 to slightly over 1.00, with high being the most aerodynamic, and low being the least. Very-low-drag bullets with BCs ≥ 1.10 can be designed and produced on special lathes using mono-metal rods.

What is the highest ballistic coefficient?

Ballistic coefficient is typically measured with a 3 digit expression. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. The higher the number, the less drag the projectile will experience.

What do ballistic coefficient numbers mean?

Ballistic Coefficients are measures of objects' abilities to overcome air resistance mid-flight. Typically, the higher the number, the lower the drag of the projectile (low negative acceleration), and the better the bullet will cut through the air.
