[QUOTE="Bob Wright, post: 1518391, member: 104363"] However, the math is well known to determine friction in air under all other atmospheric stuff. They also knew that the plastic tips they previously used would melt at "X" degrees. It's just too simple.... They mentioned they purchased doppler to measure downrange ballistics. You can derive a ballistic coefficient by drop at distance if speed at the muzzle is known along with that moments atmospherics/climate. That's what got my attention. Why is it new info, Hornady? Hornady knew it before they bought a doppler. Doppler just speeds up the calculations at multiple distances on the same shot. Any aero guy would take drop data and the climate into account and give us an accurate BC. Aerospace guys would be embarrassed if they couldn't give >98% accuracy. I just don't buy it. The bullet may perform much better and hope it does....thats the only part I like of this story. [/QUOTE]
