G1 vs G7 ??? Am I crazy 6.5 PRC

[Sierra Hunter]

I’m using the g7 as the input for BC, but the data I’m getting back makes me think I’m missing something. Am I really only getting reliable bullets expansion at 1,800 fps to 475 yds? Please help me learn here.

G1 is .625 on that round.

The .315 is the G7

 

[Sierra Hunter]

But shouldn’t I be using the G7? Of .315?

 

[BearGuy]

You have G1 selected on your app as the drag function not G7

Yes, but you are using G1.
