7mm 180 Hybrid BC question?

[pmarauder]

Does anyone have any BC data on a 7mm 180 Hybrid that has been trimmed and pointed? After sorting them by bearing surface, I get an average trim amount of around .010 length reduction and then point them up with the Whiddon. Im sure a few of you guys have some data on this? If im shooting them at 2950 fps, what will be the impact change at 1000?
Thanks

The box my bullets came in says:

G7 BC is .345
G1 BC is .674

Yes, I already know that the standard BC is .674..... Says so right on the ol' box. Perhaps my question needs to be more specific. Im looking to find data on what the "new" BC would become after I trim and point the 180 Hybrid.
Thanks

Bryan Litz states approximately an 8% increase in BC when pointing the Hybrid bullets in 7mm. I am not sure what loss you get with meplat trimming, I have heard anywhere from 2-4%. Hope that helps.

.674 + 8% = .72792

.674 + 5% = .7077
