Anyone know the BC of the Norma 6.5 130g VLD?

I cant seem to find it anywhere...

Thanks in advance.

Published is .548, but NECO says "independent testing" puts it at .590.

This is the average BC you'll get if you use an Oehler 43 Chronograph...

At the Norwegian Norma website the 6.5mm 130gr Diamond Line bullet is specified with a BC 0.548

It is definately higher than .548. The 123 LAPUA is .547,if I remember correctly) and the 130 is no doubt higher.

I am not certain I agree with that - the 123 Lapua has a much shorter bearing surface with a pretty long front end and a pretty good size boat tail. The 130 Norma has an exceptionally long bearing surface,longer than a 142 Sierra) and a more blunt front end and boat tail. It seems that Norma bullet was originally designed for a chamber like the old military 6.5 x 55's that were designed to shoot bullets with a more blunt ogive and a long bearing surface.

I havent tested the b.c.'s of each but the 130 seemed to do better in the wind in my 6.5 Grendel bolt rifle. There was not a significant difference, but I did notice a difference.
I had a VERY hard time trying to work up a load with the 130's. They were very seating depth sensative.
