Too much variance in bullet specs?

[Jody Simcox]

I think BTO is the worst measure, and as demonstrated here really.
With BTO you don't know what it means, so you couldn't credibly act on it.
Has his ogive radius shifted datum? Bearing length? Base length?
Would you act on each or their summation the same?

My single measure is ogive radius, with meplats pointed.
Both meplats and nose shape affect BC.
What happens behind the ogive datum is difficult to define, and matters less anyway.

You’re a lot further down the rabbit hole than I am…and I do know what BTO means to me…available case capacity has decreased when a bullet has a longer BTO…also, neck/bullet interference has increased…just wondering if anyone knew what I should expect on a target….I’ll shoot what I’ve got and find out…
