I just ran two charts on my Barnes bullet. BC of .47 out to 1000 yards one using G1 the other using G7 with all data entry the same. there is 90 inches difference in drop according to the 2 charts. is that even possible !! According to the charts I ran using my bullistics app , the Leica data is for sure still using G1 drag calculation. The chart on the Leica site was within 1/2 inch of drop at 1000yds as my G1 chart from another source. If there is 90 inches diff at 1000 yds using g7 drag vs G1 drag then the Leica needs to be able to choose but it is my understanding it only uses g1.
I am using the 169gr Barnes tipped triple shock (300wsm)which recommends using G7 for ballistics calculations.
Nothing is standard issue in this world anymore!!!
