Ray, I understand the question. My answer is, there's more than one way to skin a cat. Or find an accurate load. Or use the results of a ladder test.
Personally, I've tried them. Now I just find a load that shoots good at 100 and then stretch it out and see if it holds up at long range. Works for me.
I guess that just shows my inexperience with long range shooting too, but that's a burden I'll have to bear.
