The bullet was a Hornady 6.5 CM 140 grain ELD match and input variables were exactly the same. Out to 1,000 yards the come up (MOA) was pretty close. After 1,000 yards the variance increased 1,100 -1.27moa, 1,200 - 1.85moa, 1,300 - 2.70moa, 1,400 - 3.87moa, 1,500 - 5.33moa, 1,600 - 7.05moa, 1700 - 8.86moa, and 1,760 - 9.97moa.
Using a BC of G7 or 4DOF appears to make a difference at longer distances. Hope my data is correctly presented.

That’s why I like 4DOF: you can tweak the muzzle velocity to adjust for POI inside 600 yds and tweak the BC beyond 600 yds to get the software to match the bullet and your load on the day and place you’re shooting it.

As @lowlight says: “Believe the bullet!”
