Re: Actual BC of Berger bullets???
I have tested the .264 140 grain Berger VLD at my local shooting range which is about 5000 ft. elevation. Berger rates that bullet at .627 and my testing of bc at 500 yards was .704. I talked to another fellow awhile back that said the 210 VLD measured something like .690 at about 3000 ft. elevation. He was shooting a 300 Wby.
Berger rates their bullets at a range in California which is somewhere around 1000 foot elevation so if you are close to that elevation, your bullets should be close to the same. I say close because there is literally 100 reasons for bc's to differ. I will list a few just for kicks and giggles.
3. ambient air temp
5. ogive length
6. wind direction
7. bullet jacket condition
8. barrel condition
9. barrel vibration
10. air density/barometric pressure
11. stability/correct twists
12. number of grooves in barrel
And there are many other factors which get real technical.
So, as you can see, the factory rating is just a starting point. You could have a higher or lower bc!
Good shooting. --goodgrouper [img]/ubbthreads/images/graemlins/grin.gif[/img]
