I could very well be doing something wrong.. To be honest I am new at the long range game.. I am just running the numbers through my Shooter App with my phone.. The G1 mode shows a BC of .431 ... For the G7 mode all that shows is the selection for that mode, the BC numbers don't show.. Like you said, there sure seems to be a big difference between the two..

Re: G1 vs G7

As you can see below, up to 800 yards there's really no concern with vertical adjustment.

trace1 = using G1
trace2 = using G7

BC for G7 was calculated by the program.

Re: G1 vs G7

BuckSnort,

The large difference you're seeing between the two suggests there is something wrong with the calculation; there should not be that much of a difference. I suspect the program is using a G1 BC when it's running in 'G7 mode', or vise versa.

What bullet are you using? I'll try to re-create your results in Shooter and help sort it out if I can.

Thank you for you're time.. I'm gonna be shooting 130 TSX @ 3100 (hopefully) I actually have not loaded them yet but my rifle shoots the 140 TSX good but I only have a few left so I figured I'd switch to the 130's for the higher BC..
