G1/G7 ballistic coefficient diffrences

[seadog]

Here is an example.

Fps BCg1 BCg7
1500. 0.565. 0.314
2000. 0.629. 0.317
2500. 0.651. 0.327
3000. 0.678. 0.332

Those numbers are for Hornady .338 250gr BTHP Match.

And of course you probably already know this but I'll say it anyway.
G1 looks like a pistol bullet,flat base and rounded ogive.
G7 has a boat tail and a pointy ogive.
So G7 data reflects most modern bullet designs.
