[QUOTE="VTbluegrass, post: 2583423, member: 104786"] Arguing two different drags(not they/them drags) but physical drags. Hammer bullet design reduces bearing surface drag created by contact with the barrel which is very simple physics and I doubt Mr. Steve was thinking about air drag once it leaves the barrel; with the obvious exception proven design features such a boat tail and and fairly pointy front end. At ballistic speeds especially after facing deformation by rifling it would take a hell of a lot of research to determine PDR grooves impact on air drag/lift. Which again I doubt was their purpose based on Steve’s responses. [/QUOTE]
