Changed Berger B.C.

[trueblue]

Can anyone tell me if and why Berger changed their BC rating on their Match VLD bullets. I got an order of 7mm 168gr Match VLD and their website shows a BC of .643, but the box read .617. Also ordered some 30cal 210gr Match VLD and their website showed a BC of .631, but the box said .575.



7mm 168gr VLD - .643 / .617
30cal 210gr VLD- .631 / .575 (lower BC than SMK)

Anyone know what is going on?

They hired a new ballistician and are changing advertised BCs to more closely match actual figures I believe.

Thats probably the case. But it surprises me because I seem to always have a higher than advertised BC with the VLD bullets when I shoot the calculated drops.

I might be off base also, it seems I read something about this somewhere though. Going to the source would get the correct answer of course instead of my internet speculation.

Me too!!

For the 6mm 115 VLD, the BC is right on to a little low, according to my drops shot at Quantico, Va which is near sea level.

Called Berger several times today, left message for someone to call me back, but have not got a response as of yet. It seems strange that the revised BC would be lower, and by quite abit lower with the 30 cal 210 VLD. It doesn't seem right that Berger's 210gr VLD @ a .575 BC would have a lower BC than Sierra's 210 MK., which is .645.

I would guess they are changing the speed at wich the BC is measured.
