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.

.315 is very optimistic, you may need to lower that a little as your target distance increases

This. Their mach 2.25 BC is for distances where BC is a much smaller factor. Applied Ballistics' measured BC aligns with Hornady's mach 1.75 BC (0.294).
