Help with some ammo

[bnewt3]

Ive got a box of Aguila 308 and Aguila 7.62x51 both 150gr, their website says they are identical by the velocity and energy at the muzzle and @100yds, but there is no mention of the BC or drop. Can I calculate BC from MV & 100yd velocity?

Not really but you could probably estimate it close enough based on similar bullets and then shoot it at distance to fine tune

Lucky gunner has it listed as 0.393 G1 . A good place to start and true up from there.

Sounds about right, Hornady's 150gr FMJBT is .398
