Well, what I do know is this:
1. .... I've deduced that they know way more about LR hunting/shooting than 99% of the people on the planet, including you.
4. The "names" are very fond of the .308/168's/IMR 8308 for some reason.
Sorry to burst your bubble, but your deduction may be completely wrong. You don't know me or anything about what I know. Also, if the "names" are fond of a .308 Winchester/168 grain combo for anything that can be called Long Range, they don't know as much as you think either.
