G7 BCs for .270

[Henry Straker]

Does anyone know the G7 BC for:
- 130gr Nosler Ballistic Silver Tips
- 130gr Nosler E-tips,

or know where I might be able to find these out? I know it can be figured out on the range with the use of a ballistics' calculator but I was hoping someone might have gone through all the trouble already?!

The Nosler site shows the silver tip with a BC of .433
The E tip at .459.

Why the inquiry for the BC of a hunting bullet?
