I trying to get a BC for some 7.62 Nato ammo I have. It's South African surplus ammo and it is 147 gr. Other than that, I know nothing about it. I would like to work up a range card for this ammo since I have 500 rounds of it. Unfortunately, all the ballistic programs need a BC to draw up a drop chart.

My question is ..... how do you figure out a BC for an unknown bullet???
