Federal Cartridge BC?

[zxcv]

I'm looking for the BC for Federal 180gr SP Power-Shok ammo in .308. I've looked everywhere and can't find the info.

Thanks,

B

First find out for sure what bullet it uses...is it a 180gr Sierra Gameking? If so, the BC is said to be .4

Check out this website for all your BC needs:

google JBM ballistics and click on the 'ballistic coefficient' link. Enter the factory ammo velocity specs and the yardages and hit enter

OP, how accurately do you need to know? Considering you don't know what your muzzle velocity is, the BC won't help much on its own. The best answer to find what your trajectory is is to shoot at different ranges and record your results.
