Javelin slugs are designed to travel long distances with minimal influence from external factors. To do this they incorporate a tangent ogive and smooth shank which reduce drag through the air. They also ensured that the weight distribution and balance provides stable flight, even in turbulent conditions. This ensures an optimum BC across a broad range of barrel designs, twist rates and velocities.
The combination of soft lead, a deep hollow point and a large Hollow Point mean that explosive expansion takes place on impact, dumping most of its energy within the first few inches.
BC values are measured over 100 Meters and listed as RA4 drag functions for more accurate calculations.
