I have been loading some Berger 150 Hunting VLD (B.C. .518) for my 270 WSM and ran out. I went to buy some more, but I noticed that these new ones I bought said the B.C's are .531. I didn't think Berger's made B.C's .531 so I checked their web-site and it says .518. So I am confused as to weather these are mis-printed or are these their new B.C's? Also, if they are in fact .531 will it change my data much if I load them? Any input greatly appreciated.
