Just add the two distances and drops together? That doesn’t seem right. Surely it would exponential, the drop at 4X the distance being much more than the 28 ft that method results in.
I really don’t know.
The furthest out I’ve shot was 300 yards.
That was so long ago that I’ve forgotten how far over the target I aimed. And I wasn’t using a Mosy.
Actually, now that I look at the chart more closely, it bears out what you’re saying.
Two and one half times the distance resulted in a five fold increase in drop. So at an even greater distance, the increase would (I suppose) be even more dramatic.
