[QUOTE="Beng, post: 904511, member: 37512"] Hard to say, the right one seems to have an longer boat tail of a more efficient angle. [s]Got to take some measurements.[/s] I took a few very crude measurements, .1 cal difference in boat tail length, about 3° difference in boat tail angle. The right projectile is definitely not inefficient, I can't judge the impact of the difference in nose design though. I'd say they are either similar in their respective drag numbers, or the right one has a lower Cd. [/QUOTE]
