does anyone know the actual ballistic coeffiecient (sp) of the noe 432-277 keith SWC? I was looking up the ballistic calculator at handloads.com and the BC calculator there says .182, but that's just from choosing the SWC/HP option, which might be close, but I'm not confident on how close. also, has anyone had experience with these boolits (E.K's not just noe) with a cup point? seems that it would help some, while not limiting penetration too much, and also not as likely to shatter on impact. thanks!
