Re: 7.62x51(308) ballistics??

Tough to shoot drop data without stretching it out a bit (400 yards +). I have no info on your specific ammo, but If you punch in 2800fps and use a .380 G1 BC it should get you on paper when you can stretch it out a bit.

Once you have the real speed and the real drops at a longer range, just tweek the BC in your program until it matches what your rifle does at the ranges you shot and then you will know the BC and your chart will be good to go.

I build drop dials as part of my work and many bullet/load combinations require a BC other than whats published to get an accurate set of drops..

You mentioned it is a battle pack. From South Africa maybe?

Anyway it is loaded to NATO 7.62x51 spec and you can go to wikapedia and look at the specs or google Nato 7.62x51 and there are lots of references.
