That is a very good point, and exactly the answer I was hoping for.
I forgot about G7 BCs as mostly G1's are thrown around.

BUT, Just done a bit of research and with JBM comparing Berger 185gr with G7 of 0.291 doing 2550fps, compared to 155gr Berger G7 0.247 doing 2950fps.
The 155gr will buck the wind better and have less drop out to 1100 yards, and will also have more energy out to 800yards.
After 1100yards the 185gr will buck the wind better, but the 155gr will still have much less drop.

Tis all very interesting this ballistics stuff.
