How can you claim such high BCs?

All ballistic coefficients (BCs) were determined using Doppler radar by measuring bullet velocity as a function of distance to ranges of up to one mile. Doppler radar provides velocity measurements roughly every one to two feet of the bullet's flight, resulting in exact measurements of velocity loss due to drag. By using state-of-the-art aeroballistics software (6DOF), large amounts of data can be analyzed and computed to provide extremely accurate determinations of projectile drag.
