It's interesting you mention this. I was discussing this issue with my friend down at camp. He and I are both Buckeye transplants. He moved down 12 years ago; his wife was from the county. She died, and now he lives close to her brother over on the next ridge. He is known as "Blacksmith" on my weblog.
He is a big fan of 45-70. However, we were discussing the various chamberings we'd encountered down here.
His web of kin are all hugely vested in 270 WIN going back at least a couple of generations.
Previously, I had known few male hunters here in the general area that favored 270 WIN. When it was chosen, it was usually what a husband bought his wife for hunting.
