Now that you have the scope adjustment figured out that makes hitting at long range much easier. I was playing with my isnipe app and can’t quite line up with your measured drops, but I can get close.
I used 3120fps, g7bc of 3.18 and I used an average pressure that I would see here (I live at 3100’).
At 300 yards I have 3/4” more drop, at 500 1” more drop at 600 I have 3” more drop. The 400 I can’t seem to get close I am always roughly 4” more drop no matter what I change I can’t close the gap.
When you look at what group sizes would be using your 1/2moa groups the 300/500/600 actually line up fairly well. The 400 would be an outlier. To get closer calcs I would need you scope height and actual air pressure.
With your actual measured drops, and knowing what your scope actually adjusts you should be able to make hits out to 600. I would try and do some paper shooting before game but you are fairly close.
If it helps my scope height is 1.77”. Thanks for taking the time to run the calculations. Based on my recent test of colder cartridges I think my actual MV is going to be significantly less than 3100.
Based I what I know right now I am going to limit my hunting to 400y. Maybe when I have more experience in testing at longer distances I can increase my comfortable range.
